1 Safety and requirements for product use
1.1 Safety
1.1.1 General safety information

Warning
Danger of injury
If there is an error (e.g. fieldbus interruption, PLC failure, no voltage) on the MSE6-E2M,
then the shut-off valve switches to the initial position (pressurise). If there is a previ-
ously shut-off valve, the system is pressurised suddenly.
• Use suitable measures to ensure that, in case of error, unintentional pressurization
of the system does not result in a hazard.
Warning
Danger of injury due to residual pressure
When venting the system via the MSE6-E2M, a residual pressure P2 < of 1 bar remains.
• Use appropriate measures to ensure that the residual pressure does not result in a
hazard.
Please note
Damage to the product from incorrect handling.
• Switch off the compressed air and supply voltage before performing assembly and
installation work. Switch on supply voltage only when assembly and installation
work are completely finished.
• Observe the handling specifications for electrostatically-sensitive devices.
Please note
The compressed air must not contain ester oils.
1.1.2 Intended use

The energy efficiency module MSE6-E2M is intended for installation in a machine or automated system
and must be used exclusively as follows:
– In perfect technical condition
– In original status, without unauthorised modifications
– Within the limits of the product defined by the technical data ( Appendix A)
– In an industrial environment

1.1.3 Foreseeable misuse

Please note
In the event of damage caused by unauthorised manipulation or other than intended
use, the guarantee is invalidated and the manufacturer is not liable for damages.
The following foreseeable misuses are among those not approved as intended use:
– Use outdoors
– Shutting off a system as a safety function
– Use in safety functions:
– The MSE6-E2M must not be installed behind an exhaust valve that fulfils a safety function, since
otherwise the safety functions installed in the system can be impeded.
– For an installation of the MSE6-E2M in front of a safety valve, it must be ensured that this layout
is expressly allowed for the safety valve. For example, mounting of the MSE6-E2M in front of a
soft-start/quick exhaust valve MS6-SV-...-E-... is not permissible.

2 Overview
2.1.2 Mode of operation
Machine/
system
Fig. 2.2 Typical mounting position
The MSE6-E2M is typically assembled behind a service unit combination.

It allows venting of the following system, both in the “Pressurise” state and in the “Shut-
off ” state through a reverse flow (2 1). In the shut-off state, the reverse flow is consid-
erably reduced. For this reason, for more rapid venting, the MSE6-E2M should be in the
“Pressurise” state.
The key functions are:
Standby detection and automatic shut-off of the compressed air supply

The MSE6-E2M uses settable parameters to detect production down times of a pneumatic system. The
system is separated from the compressed air supply using the 2/2 shut-off valve, without venting the
subsequent system. This avoids additional air consumption through leakages. If production is to con-
tinue on the system, then it must be signalled to the MSE6-E2M. The shut-off valve opens and the sys-
tem is again supplied with compressed air.
Automatic shut-off of the compressed air supply can be activated and deactivated by the user. In the
deactivated state, the shut-off valve can be controlled directly by the PLC.
Pressure tightness testing

When in the shut-off state, the MSE6-E2M measures the pressure curve over time.
Even in well-serviced systems, the pressure falls continuously due to leakages. The fewer leakages the
system has, the slower the pressure drop will be. The measured pressure change serves as a measure
of the leakage existing in the system. If the parameterised limit value is exceeded, then the device will
output a diagnostic message.
Pressure recording
The MSE6-E2M continuously measures the output pressure, prepares the data and makes it available
cyclically.
To detect high operating pressures, the MSE6-E2M offers the option of parameterising limit values for
pressure. If the parameterised limit value is exceeded, then the device will output a diagnostic mes-
sage.

2 Overview
Flow recording
The MSE6-E2M continuously records the flow, prepares the data and makes it available cyclically.
To detect high flow rates, the MSE6-E2M offers the option of parameterising limit values for the flow. If
the parameterised limit value is exceeded, then the device will output a diagnostic message.
Consumption recording
The MSE6-E2M determines the compressed air consumption by recording the system flow rate. The
user has the option of using appropriate signalling to record the compressed air consumption over a
specific period of time.
2.2 Commissioning, diagnostics and operational functions

The system reaction of the MSE6-E2M can be adapted to the relevant application. The MSE6-E2M
provides extensive functions for commissioning, diagnosis and operation.
Commissioning and operational functions

The MSE6-E2M is supplied from the factory with preset parameters.
The behaviour of the MSE6-E2M can be adapted to the respective requirements through parameterisa-
tion. The following behaviour can be influenced, for example, by accessing the internal parameters:
– The diagnostic behaviour by enabling maskable diagnostic messages
– Specification of the units and the measuring interval
– Setting of limit values
– The operating method of the diagnostic memory.
Caution
A different parameterisation will result in different characteristics.
• In particular, check which settings are required when replacing the MSE6-E2M.
• Ensure that the settings can be restored (e.g. in the start-up phase by the higher-or-
der PLC / IPC).
Basic information on the different parameters can be found in Chapter 7 and C in this
description.

2 Overview
Diagnostic functions
Extensive diagnostic information can be accessed depending on the fieldbus used.
Diagnostic information Brief description
Status bits Common diagnostic messages (global error messages) are displayed by
means of 8 internal inputs (8 status bits).
I/O diagnostics With fieldbuses that do not possess extensive diagnostic functions, the
interface diagnostic information of the MSE6-E2M is available via the I/O diagnostic
interface. The I/O diagnostic interface enables bus-independent access to
diagnostic information, data and parameters via internal digital I/Os
(16 inputs and 16 outputs).
Diagnostic memory Errors which occur during operation are entered in a diagnostic memory.
The first or the last 40 entries are saved, as well as the respective time
measured from the moment the power supply was switched on.
Fieldbus-specific Special diagnostic functions or communication services are available,
diagnostic functions depending on the fieldbus used, for example communication services via:
– DPV1 (PROFIBUS)

ments of loose tubing lines can cause injury to people or material damage.
Before carrying out mounting, installation and maintenance work, switch off the follow-
ing:
• Compressed air supply including venting of the system
• Operating and load voltage supplies.
Pay particular attention to the following:

• Screw connections must be fitted without warping and mechanical stress. Position
screws exactly before tightening (otherwise their threads will be damaged).
• Observation of the specified tightening torques.
• Contact surfaces must be clean (avoid leakage and contact errors).
• Seal the unused connections with the protective caps or blanking plugs, in order to
achieve the IP65 degree of protection.
• Electrostatically-sensitive devices.
Do not touch the contact surfaces of the plug connectors on the modules and com-
ponents.

3.2 Mounting
Note
Fit the MSE6-E2M so that there is sufficient space for heat dissipation and ensure that
the maximum limit values for temperatures are observed ( Technical data).
Note
Place the MSE6-E2M in such a position in your system that the necessary air quality
class for the operating medium is maintained ( Technical Data).
The MSE6-E2M is intended for mounting on the wall. The mounting brackets are integrated and contain
drill holes for wall mounting.

hazard.
3.4.2 Settings for configuration on the fieldbus module

The characteristics of the MSE6-E2M can be adapted to various requirements. Important application-
specific settings can be made with DIL switches directly on the fieldbus module.
1 Service interface, operator unit 3 DIL switch

2 Fieldbus connection (Sub-D, 9-pin)
Fig. 3.3 Fieldbus module with DIL switch

Settings on the bus node

The fieldbus is connected via the integrated fieldbus module, which is matched to the appropriate
fieldbus type. Setting options may vary according to the fieldbus type.
The fieldbus-specific settings can be made with DIL switches on the module. The DIL switches are be-
hind an easily accessible cover on the bus node.
Information on the method of procedure as well as on the setting possibilities on your

fieldbus module Section 4.3.
3.4.3 Selection of the power supply unit

Warning
• Use only PELV circuits in accordance with IEC/DIN EN 60204-1 (protective extra-low
voltage, PELV) for the electrical power supply.
Also observe the general requirements for PELV circuits in accordance with
IEC/DIN EN 60204-1.
• Use only power sources which guarantee reliable electrical separation of the operat-
ing voltage as per IEC/DIN EN 60204-1.
Protection against electric shock (protection against direct and indirect contact) is guaranteed in ac-
cordance with IEC/DIN EN 60204-1 by using PELV circuits (Electrical equipment of machines, general
requirements).
Recommendation:
• Use regulated power supplies to ensure that the load voltage of the outputs remains within the
permitted tolerances even during continuous operation.
Note
• When selecting the power supplies, check that they have sufficient output.

3.4.4 Power supply of the MSE6-E2M

Warning
Danger of injury
If the load of operating voltage of the MSE6-E2M is switched off, then the shut-off valve
switches to the initial position (pressurise). If there is a previously shut-off valve, the
system is pressurised suddenly.
• Use suitable measures to ensure that unintentional pressurisation of the system is
not possible.
Note
Check within the framework of your EMERGENCY OFF system to ascertain the measures
necessary for putting your machine/system into a safe state in the event of an EMER-
GENCY OFF (e.g. switching off the load voltage for the valves, switching off the com-
pressed air, etc.).
If there is an undervoltage, the MSE6-E2M switches to the “Pressurise” status.
Note
Note that the partially lower tolerance range must be observed when the operating and
load voltage supplies are provided by a shared power unit.
Tolerance ranges:
– Operating voltage: ±25%
– Load voltage: -25%,
+10%
Supply of the operating and load voltage

– The load voltage supplied will be available to the integrated module.
– The operating voltage supply is transmitted without interruption.
Pin allocation
Caution
Short circuits can cause damage.
• Secure the system supplies externally.
The permissible current per pin at the supplies is:
– M18 plug, 4-pin: max. 16 A
• Please note that with the 4-pin system supply via pin “0 V”, the sum of both currents
of the operating and load voltages flows.

Potential equalisation
The MSE6-E2M has two earth terminals for potential equalisation:
– Pin 4 (M18 plug) on the power supply connection of the system supply
– Earth terminal on the left-hand end place of the electrical interlinking module
– Earth terminal on left-hand pneumatic base plate
Note
• Always connect the earth potential to pin 4 (M18 plug) “functional earth”.
• Connect the earth terminal on the left-hand pneumatic base plate with low imped-
ance (short cable with large cross-sectional area) to the left end plate of the electric-
al interlinking module (pre-assembled on delivery).
• Connect the earth terminal on the left-hand end place of the electrical interlinking
module with low impedance to the earth potential.
• With low-impedance connections you can ensure that the earth terminal at the left-
hand end plate and the earth terminal at the power supply connection have the
same potential and that there are no equalising currents.
This prevents interference from electromagnetic sources and ensures electromagnetic
compatibility in accordance with EMC directives.

Electrical connection example

The diagram below shows as an example the connection of a common 24 V power supply for pins 1
and 2 on the M18 plug. Observe the following:
– Maintain the lower tolerance of the load supply voltage (24 V DC actuator +10/-25 %).
– Connect the earth terminals for potential equalisation and ensure that compensating currents are
prevented.
– Apply the load voltage at pin 2 of the M18 plug (actuator technology) in which a way that it can be
switched off separately.
– Use external fuses, depending on the application (total maximum value at pin “0 V” for both fuses:
16 A).

Warning
Danger of injury
Stopping the controller (e.g. after the transmission of parameters, system configuration
or controller program) interrupts the communication to the MSE6-E2M and the shut-off
valve then switches to the initial position (pressurise). If there is a previously shut-off
valve, the system is pressurised suddenly.
• Use appropriate measures to ensure that unintentional pressurisation of the system
is not possible.
Warning
Danger of injury
If the load or operating voltage of the MSE6-E2M is switched off, then the shut-off valve
switches to the initial position (pressurise). If there is a previously shut-off valve, the
system is pressurised suddenly.
• Use appropriate measures to ensure that unintentional pressurisation of the system
is not possible.
The MSE6-E2M is equipped with a pneumatically-piloted shut-off valve. When the input pressure P1 is
applied, the valve automatically switches to the “Pressurise” state in the following cases:
– Switch-off of the operating voltage or the load voltage
– Interruption in fieldbus communication
– Stopping of the fieldbus master controller (see manufacturer's specifications), e.g. in the case of
the transmission of control programs, parameters, configuration data.

4.1 Procedure
In order to avoid connecting and addressing errors, you should carry out commissioning in steps as
follows. The individual commissioning steps are shown in the diagram below.
1 Step 1 – Checking of the connected pneumatic application

2 Step 2 – Commissioning on the fieldbus with testing of the address allocation
Fig. 4.1 Commissioning steps

4 Commissioning
4.2 Prior to commissioning

The connection is made via the bus node that is adapted to suit the fieldbus.
The characteristics of the MSE6-E2M can be adapted to various requirements. You can carry out im-
portant settings as follows:
– With the DIL switch directly on the bus node ( Section 4.3.3).
– By parameterisation ( Section 4.2.2).
The DIL switches and the parameters are preset at the factory.
Caution
Incorrectly set DIL switches and parameters can cause damage during operation. You
must observe the following notes in order to prevent damage.
• Check the DIL switch settings before using or replacing a MSE6-E2M.

• Make sure that the desired parameterisation of the MSE6-E2M in the start-up phase or after field-
bus interruptions is carried out by the plug-in module or the scanner/bus master, providing this is
supported by the fieldbus protocol used. This ensures that, after replacement, the new MSE6-E2M
will also be operated with the desired parameter settings.
Preparations
Prepare the MSE6-E2M for commissioning before commissioning a fieldbus system.
Note
Do not connect the cables for the fieldbus connection when preparing for commission-
ing.
In this way, you can avoid:

– Addressing faults which may occur in various fieldbus systems when address ranges are modified
during operation.
Proceed with preparation as follows:
1. Check the pneumatic tubing connection of the MSE6-E2M.
2. Check the electric cabling of the MSE6-E2M.
3. Check the DIL switch settings of your MSE6-E2M.

4.2.2 Types of parameters

The parameters are preset at the factory. These presettings can be used for a large number of applica-
tions. Through parameterisation, the behaviour of the MSE6-E2M can be adapted to each particular
application.
The options available depend on the fieldbus protocol used. You can find information on
this in the description of the CPX bus node ( Tab. 1).
A distinction is made between the following types of parameters:

Types of parameters Description

4.4 Start-up behaviour

The desired parameterisation should be carried out in the start-up phase or after fieldbus interrup-
tions by the interface module or the scanner/bus master, providing this is supported by the fieldbus
protocol used. In this way, you can be sure that when the MSE6-E2M has been replaced, the new ter-
minal is operated with the same parameter settings.
You can influence the start-up behaviour with the aid of the system parameter System start ( Sec-
tion 4.2.2). Select the setting “System start with default parameterisation and current CPX expansion”.
The desired parameterisation can then be created in the start-up phase or after fieldbus interruptions
e.g. by the plug-in module or the scanner/bus master (depending on the fieldbus used).
If the M LED lights up permanently after system start-up, then “System start with saved parameterisa-
tion and current CPX expansion” is set.
Caution
If the M-LED lights up permanently, parameterisation will not be restored automatically
by the higher-order system if the MSE6-E2M is replaced after servicing. In these cases,
check before replacing to see which settings are required and carry out these settings.
Detailed notes can be found in the description for the appropriate CPX fieldbus module or
the manual for the operator unit.

5 Measurement and control functions

The following sections provide an overview of the individual measurement and control functions of the
MSE6-E2M and present their setting options and their influencing variables.
Individual functions and their behaviour can be controlled using the outputs and/or parameters. Meas-
urement and status signals are available as input values. Diagnostic information is made available as a
combination of the error number and their channel allocation.
5.1 Flow
Input signal
The measured flow value is prepared according to the set parameters “Flow unit” (P8.2-8.3) and “Flow
standard” (P8.6-8.7) and made available as an input signal (Em.0).
Limit value monitoring
A comparator is used to compare the flow measured value with the parameter “Upper limit flow”
(P11-P12). When the time set in the parameter “Monitor limit values startup” (P7) has elapsed and limit
value monitoring is activated (P0.6), the appropriate error/diagnostic message is output on violation of
a limit value.
Monitoring of parameters
The parameters “Unit flow”, (P8.2-8.3), “Flow standard” (P8.6-8.7), “Upper limit flow” (P11-12) and
“Monitor limit values startup” (P7) are checked on entry for permitted values. In case of error, if para-
meterisation error monitoring is activated (P0.7), the appropriate error message is output.
Sensor monitoring
If there is a sensor error, the appropriate error message, which cannot be deactivated, is output.

5.2 Consumption
Input signal
The consumption value is based on the prepared flow measured value. The value is prepared according
to the parameters “Unit consumption” (P8.4-8.5) and “Flow standard” (P8.6-8.7) and made available
as an input signal (Em.1).
If there is a change to the parameter values “Unit flow” or “Flow standard”, the measured
consumption value is reset to the value “0”.
If there is a change to the parameter value “Unit consumption”, then the current meas-
ured consumption value is saved and is converted to the new consumption unit.
Consumption measurement
Consumption measurement is controlled using two data bits in the output word Am.0. Consumption
measurement is started, continued or stopped using the output “Control bit Consumption measure-
ment” (Am.0.12). The measured consumption value can be reset to the value “0” using the output
“Reset consumption measurement” (Am.0.13).
The parameters “Unit flow”, (P8.2-8.3), “Flow standard” (P8.6-8.7) and “Unit consumption” (P8.4-8.5)
are checked on entry for permitted values. In case of error, if parameterisation error monitoring is activ-
ated (P0.7), the appropriate error message is output.

5.3 Pressure
Input signal
The measured pressure value is prepared according to the set parameter “Unit pressure” (P8.0-8.1)
and made available as an input signal (Em.2).

A comparator is used to compare the measured pressure value with the parameter “Upper limit pres-
sure” (P13-14). When the time set in the parameter “Monitor limit values startup” (P7) has elapsed and
limit value monitoring is activated (P0.6), the appropriate error/diagnostic message is output on viola-
tion of a limit value.
The parameters “Unit pressure”, (P8.0-8.1), “Upper limit pressure” (P13-14) and “Monitor limit values
startup” (P7) are checked on entry for permitted values. In case of error, if parameterisation error mon-
itoring is activated (P0.7), the appropriate error message is output.

5.4 Pressure change
5.4.1 Method of measurement

The pressure change DP2 is determined cyclically at intervals, the settable pressure change sample
time DT. To determine the differential pressure, the difference between the current measured pressure
value and the measured pressure value P2, based on the pressure change sample time, is calculated:
DP2 = P2(t) - P2(t-DT); t = Current measuring time.
The start of the measuring cycle to determine the pressure change is automatically synchronised to the
activation signal of the shut-off valve. The current pressure change value DP2 remains constant up to
the next measuring time point.
In the shut-off state, the amount of the pressure change value is compared to the upper pressure
change limit value DP2_OGR and monitored for violation of the limit value. If limit value diagnostics are
activated, a diagnostic message is generated when:
ABS(DP2) > DP2_OGR.

– Time diagram 3 in Fig. 5.4 shows the derived amount with a sample limit value violation at the start

5.4.2 Function structure
Input signal
The pressure change sample value is prepared according to the set parameters “Pressure unit”
(P8.0-8.1) and “Flow standard” (P10) and made available as an input signal (Em.5).

If the shut-off valve is in the “Shut-off ” state, the amount of the measured pressure change is com-
pared with the parameter “Upper limit pressure change” (P15-16) using a comparator. If limit value
monitoring is activated (P0.6), the appropriate error/diagnostic message is output on violation of a
limit value.
The parameters “Unit pressure”, (P8.0-8.1), “Pressure change sample time” (P10) and “Upper limit
pressure change” (P15-16) are checked on entry for permitted values. In case of error, if parameterisa-
tion error monitoring is activated (P0.7), the appropriate error message is output.

5.5 Shut-off
5.5.1 Automatic shut-off function

If the shut-off valve is in the “Pressurise” state, then, if the output “Control bit Auto shut-off ” (Am.0.1)
is activated, the measured flow is compared with the limit settable in the parameter “Auto shut-off flow
limit” (P19-20). If this limit value is not reached for the length of the value set in the parameter “Auto
shut-off delay time” (P17-18), then the shut-off valve will switch to the “Shut-off ” state.

5.5.2 User-controlled blocking

If the output “Control bit Auto shut-off ” (Am.0.1) is inactive, then the shut-off valve can be controlled
directly using the “Control bit shut-off ” output (Am.0.0). The output “Control bit Pressurise” (Am.0.2)
has no influence on the switching status of the shut-off valve.

5.5.3 Automatically controlled shut-off

The automatic shut-off function is activated when the output “Control bit Auto shut-off ” (Am.0.1) is
activated and the output “Control bit Shut-off ” (Am.0.0) is inactive. In this state, the flow measured
value is compared with the limit value set in the parameter “Auto shut-off flow limit” (P19-20). If the
limit value is underrun, the “Auto shut-off timer” is started.
The status of the timer is available in the input “Status bits Auto shut-off timer” (Em.3.4-3.5) and can
assume the following values:
RESET: The timer is reset and not started,
the shut-off valve is in the “Pressurise” state.
RUN: Timer is started,
the time delay has not yet elapsed,
the shut-off valve is in the “Pressurise” state.

the shut-off valve is in the “Shut-off ” state.

5.5.4 Switching to the pressurised state after automatically-controlled shut-off

When the “Auto shut-off timer” has expired (Status = UP), the blocked shut-off valve can only be
switched to the “Pressurise” state when controlled by the user. There are the following options for
switching:
• Flank-controlled: Positive signal flank at the output “Control bit Pressurise” (Am.0.2).
Detection of a positive flank resets the timer to the “RESET” status once only. Automatically-con-
trolled shut-off remains active.
• Level-controlled: Deactivation of the output “Control bit Auto shut-off ” (Am.0.1).
The timer remains in the “RESET” status for as long as this output is deactivated. When the “Control
bit Auto shut-off ” output is reactivated, automatically-controlled shut-off is active again.
When the timer is reset and the “Control bit Shut-off ” (Am.0.0) is deactivated, the shut-off valve
switches to the “Pressurise” state.

5.5.5 Function structure
Control shut-off valve

The shut-off valve can be controlled by the user or, with appropriate activation, automatically:
– If the output “Control bit Auto shut-off ” (Am.0.1) has been deactivated, then the shut-off valve is
switched directly using the “Control bit shut-off ” output (Am.0.0).
– When the output is activated, the shut-off valve switches to the shut-off state
– When the output is deactivated, the shut-off valve switches to the pressurise state.
– When the output “Control bit Auto shut-off ” (Am.0.1) is activated and the output “Control bit shut-
off ” (Am.0.0) is deactivated, the switching status of the shut-off valve is determined by the “Status
bit Auto shut-off timer” (Em.3.4-3.5) (timer of the function for automatic shut-off ). After the expiry
of the parameterised delay time (“Auto shut-off delay time”, P17-18), the shut-off valve is automat-
ically switched to the status “Shut-off ”.
– When the output “Control bit Shut-off ” (Am.0.0) is activated, the shut-off valve always switches to
the status “Shut-off ”, irrespective of other signal statuses.
The switching status of the shut-off valve is signalled via the input “Status bit Shut-off valve” (Em.3.0)
and the number of valve switching cycles via the parameter “Valve switching cycles” (P31-32).
Auto shut-off timer

The status of the auto shut-off timer is determined by the following input variables:
– If the parameterised value “Auto shut-off low flow limit” is underrun, a comparator activates
(P19-20) the Auto shut-off function.
– Activating the output “Control bit Auto shut-off ” (Am.0.1) activates the auto shut-off function.
– The output “Control bit Pressurise” (Am.0.2) can be used to switch the shut-off valve back to the
pressurise status after an automatic shut-off operation. Automatically-controlled shut-off remains
active.
The status of the auto shut-off timer is signalled via the input “Status bits Auto shut-off timer”
(Em.3.4-3.5).
The parameters “Unit flow”, (P8.2-8.3), “Flow standard” (P8.6-8.7) and “Auto shut-off low flow limit”
(P19-20) are checked on entry for permitted values. In case of error, if parameterisation error monitor-
ing is activated (P0.7), the appropriate error message is output.

7 Parameterisation
7.1 Parameterisation information
General notes on parameterisation

The characteristics of the MSE6-E2M can be parameterised.
Due in some cases to necessary calculations, modified parameters are not valid until they have been
thoroughly checked and saved. Until then, as in the case of invalid parameters, the previous internal
settings apply.
Depending on the parameter, no valid input data is available for up to max. 30 ms after a value modific-
ation.
Special notes on avoiding parameterisation errors

In order to avoid parameterisation errors, note the sequence described below when modifying the fol-
lowing parameters:
– Units
– Upper limit value x
Example: Parameterisation of pressure

Sequence for first or startup parameterisation (MSE6-E2M in delivery status, monitoring of paramet-
erisation errors active):
1. Set the desired unit in the module parameter “Units”.
2. Set the upper and lower limit values in the module parameter “Limit values pressure”.
Sequence for modifying the parameterisation:

1. Deactivate the monitoring for parameterisation errors in the module parameter “Monitoring”.
2. Parameterise the MSE6-E2M.
• In the “Limit values” module parameter, set the upper limit value to 32767.
• Set the desired unit in the module parameter “Unit pressure”.
• If necessary, set the upper and lower limit values in the module parameter “Limit values”.
3. Activate the monitoring for parameterisation errors in the module parameter “Monitoring”.

8.2.2 Module common error LED

Errors of the module are indicated via the module common error LED on the electrical interlinking block
and can, if necessary, be evaluated using the operator unit or a PC with diagnostic software.
The errors are indicated on the module common error LED and are reported to the bus node, dependent
on the module parametrisation, where they can be evaluated according to the fieldbus protocol used.
Specific errors of the module can be masked. Maskable errors are only indicated when the appropriate
monitoring has been activated.
The representation of the faults in the various bus nodes depends on the fieldbus pro-
tocol ( Description of the CPX bus node).
The module is equipped with a red module common error LED, which signals the presence of a module
error.

8.3 Diagnosis via status bits or the diagnostic interface

The MSE6-E2M offers the following two modes for diagnostics:
Mode Description
Status bits The status bits serve to display common diagnostic messages (global error
(System status) message). Access to the status bits is made via 8 internal inputs
( Section 8.3.1).
I/O diagnostics The I/O diagnostic interface is a fieldbus-independent diagnostic interface.
interface This can be used to read out all the internal data and parameters via 16
(System diagnostics) internal inputs and 16 outputs ( Section 8.3.2 and Appendix B). All
diagnostic information is then also available even if the fieldbus protocol
used does not offer any extensive diagnostic functions.
Tab. 8.7 Fieldbus-independent diagnostic modes
8.3.1 Structure of the status bits

Irrespective of the bus node used, the MSE6-E2M provides 8 status bits for displaying common dia-
gnostic messages (global error messages).
Status bits are configured like inputs. The input addresses, which are to be assigned to
status bits, depend on the fieldbus protocol used ( Description of the CPX bus node).
The status bits supply coded diagnostic information. Bits 0 to 3 specify the module types in which
faults have occurred. Bits 4 to 7 specify the type of fault.
Bit Diagnostic information with 1 signal Description
0 Error does not occur on the MSE6-E2M in the current equipment level.
1 Error at output Module type, on which an error has oc-
2 Error at input curred
3 Error on MSE6-E2M
4 Undervoltage Error type
5 Short circuit/overload
6 Wire break
7 Other error
Tab. 8.8 Structure of the status bits
If all status bits supply a 0 signal, no error will be reported.

If different errors occur simultaneously on different types of modules, errors cannot be

distinguished. Use the I/O diagnostic interface in order to distinguish errors clearly.
8.3.2 The I/O diagnostic interface
Organisation of internal data and parameters

Internal data and parameters of the MSE6-E2M are stored in a common memory area. With the I/O
diagnostic interface, read access can be achieved with the aid of the function number to individual
bytes of this memory area.
Parameters can be modified with the aid of fieldbus-specific functions (depending on the
fieldbus used) or using the operator unit ( Also Section 4.2.3).

Mode of operation of the I/O diagnostic interface

Detailed diagnostic information can be accessed via the I/O diagnostic interface. For example, you can
ascertain exactly on which module an error has occurred. 16 input bits and 16 output bits, through
which all diagnostic data can be retrieved, are available for accessing the system diagnostics.
The addresses of the input and output bits of the I/O diagnostic interface depend on the
fieldbus used ( Description of the CPX bus node).
Output bits The function no. of the desired data is specified in binary coded form
using the output bits A0 … A12 of the I/O diagnostic interface. The
function number is accepted when control bit A15 supplies a 1 sig-
nal.

Example 1: Check to see if there is diagnostic data

Function no. 1937 specifies whether there is diagnostic data and contains, where applicable, the num-
ber of the first module on which an error has occurred ( Section C.4).

Example 2: Read out current error numbers of module 1

With the aid of the module number of the faulty module, you can ascertain the function numbers of the
relevant module diagnostic data ( Also Section C.5). Module diagnostic data can be e.g.:
– The number of the faulty channel
– The module error number.
With the following function number, you can ascertain e.g. the module error number of module 1:
Function no. = 2008 + 4 * 1 + 1 = 2013

8.4 Error numbers

Possible errors of the MSE6-E2M are divided into three error classes with different priority, depending
on the seriousness of the error. If an error occurs, the system error LED (SF LED) will flash depending on
the error class.
Error class Flashing sequence of the SF LED Error weighting Priority
1 1 * flashes, pause time Simple (e.g. simple user error) Low
2 2 * flashes, pause time Medium (standard diagnostics and Medium
extended diagnostics)
3 3 * flashes, pause time High (hardware error/internal error) High
Tab. 8.11 Error classification
If several errors occur together, the error with the highest priority will have precedence. This means
that:
– The system error LED flashes according to the higher priority
– The number of the error with the higher priority will be entered in the system diagnostic data under
function number 1938 (error number).
Within an error class, errors of modules with a lower module number have higher priority. For example,
errors of module number 0 have the highest priority within an error class. Errors of module number 1
have the second highest priority, etc.
Overview of all possible error numbers Appendix E.

The following errors can be signalled by the function module:

A.2 Connecting cable
Fieldbus cable
Use a suitable cable for your field bus system. Refer to the manual of your controller for the cable type
to be used. Also take into account here the distance and the fieldbus baud rate.
Operating voltage cable

Use an operating voltage cable with a sufficient cable cross-section. Avoid long distances between the
power unit and the MSE6-E2M. Long operating voltage cables reduce the voltage supplied by the power
supply unit.
Preparing the connecting cable

Caution
The position of the pins on the plug is different from that on the socket!
– Pin allocation of the fieldbus interface, see manual for the appropriate fieldbus
node.
– The operating voltage and load voltage connections are in the form of plugs. Inform-
ation on the pin allocation can be found in the following chapters.
Use plugs and sockets from the Festo product range which match the outside diameter of
the cables used.
Preparing the plugs and cables

Connect the plugs and cables as follows (example):
1. Open the plugs/sockets as follows:
– Power supply socket:
• Insert the mains power socket into the operating voltage connection of the MSE6-E2M.
• Unscrew the housing of the socket.
• Then remove the connecting part of the socket which is inserted in the operating voltage
connection.

2 Strain relief 4 Connecting part
Fig. A.1 Component parts of the socket and cable throughfeed
2. Open the strain relief on the rear part of the housing. Then pass the cable through.
3. Remove 5 mm of insulation from the end of the conductors and fit wire end sleeves on the stranded
wires.
4. Connect the ends of the conductors.
5. Replace the connecting part on the housing of the plug/socket. Pull the cable back so that there are
no loops inside the housing.
6. Tighten the strain relief.

B Parameterisation examples
The following examples for determining parameters must be carried out under normal
production conditions.
B.1 Commissioning example for the automatic shut-off function

Each system must be set individually. The sample values are only intended as an orienta-
tion.
Recommended approach:
1. Recording the relevant function-specific production data
To be able to set the parameters for the automatic shut-off function of the MSE6-E2M
correctly, the following data of the following system is required ( Fig. B.1):
– Minimum flow in production operation
– Pneumatic and electrical in operation
– Actuator technology in action
– Maximum time at continuous minimum flow (e.g. production downtime)
– Maximum flow for production downtime
– Pneumatic and electrical in operation
– Actuators not in action
Short-time Short-time
production production Auto shut-off
downtime downtime Deceleration
1 Minimum flow rate in production operation 3 Maximum flow for production downtime
2 Auto shut-off low flow limit
Fig. B.1

Sample values in the “Pressurise” state:

– Minimum flow rate in production operation : 250 l/min
– Maximum pause time in production operation: 2 min
– Maximum flow for production downtime: 80 l/min
2. Set parameters for automatic shut-off function

To avoid unintentional behaviour, additional tolerances and safety additions must be
taken into account during parameterisation.
• The module must be in the “Shut-off ” state for the parameters to be effective (otherwise, the
previously set values apply).
• The “Auto shut-off ” function must be deactivated.
• Parameter “Auto shut-off delay”
Set the parameter higher than the actual pause time, in order to avoid accidental advance shut-
off, in the upper example values, for example, to 10 min.
• Parameter “Auto shut-off low flow limit”
The parameter must be higher than the maximum flow rate at rest, but lower than the minimum
flow in production operation.
In the example, it could be set between 90 and 240 l/min.
3. Activate automatic shut-off function
• The control bit “Auto shut-off ” (B1 in the output word Am.0 “Module control”) must be set.
After the set time, if there is an underrun of the flow limit value, the module should switch to the
“Shut-off ” state.
4. After automatic shut-off, switch the module back to the “Pressurise” state.
– The module has switched automatically to the “Shut-off ” state (shut-off valve closed: Status bit
Shut-off valve Em.3.0 = 1)
– The control bit “Shut-off ” (B0 in the output word “Module control”) must stay deactivated.
• Positive signal flank on control bit B2 in the output word “Module control” (automatic shut-off
function remains active)
• Otherwise, deactivation of the automatic shut-off function by resetting the control bit B1 in the
output word “Module control”; it may occur that the automatic shut-off function may need to be
reactivated.
5. Check the set values over multiple production cycles.
Changes to system parameters can lead to a change in the determined production data.
Check whether the system parameters are still valid.

B.2 Commissioning example for monitoring the pressure drop

Each system must be set individually. The sample values are only intended as an orienta-
tion.
Recommended procedure for determining the value for the parameter “Upper limit pressure change”:
1. Switch the MSE6-E2M to the “Pressurise” status.
2. Specify a value for the “Pressure change sample time” parameter.
If your system shows a high pressure drop, start with 100 ms (corresponds to parameter
value 1).
This displays the value for the pressure change every 100 ms. If there is a smaller pres-
sure drop, increase the parameter value for the “Pressure change sample time”, e. g. to
10, meaning that the pressure change every 1 s will be displayed. Vary the value for the
“Pressure change sample time”, until you have determined a suitable value for your sys-
tem.
3. Switch the MSE6-E2M to the “Shut-off ” status.

4. Record the pressure change values of the selectable input word (Em.5). For this, Am.1 must have
the value 0.
A pressure change is a signed value and, when there is a pressure drop, can thus be a
negative value.
5. Generate the amount of the pressure change (sign reversal for negative values).
6. Determine the amount of the largest pressure change value.
7. Through multiple switching from the Pressurise to the Shut-off status, determine the amount of the
maximum pressure change value.
If you have obtained very small values, it may be wise to increase the value for the para-
meter “Pressure change sample time”.
8. Specify this value, with an added safety tolerance, for the parameter “Upper limit pressure change”.
In this way, you can avoid accidental error messages.
Sample values:
– Parameter “Pressure change sample time”: 1 s
– Parameter “Upper limit pressure change”:
– Amount of maximum pressure change value: 160 mbar
– Set limit value incl. safety tolerance: 200 mbar
Monitoring of the pressure change only takes place in the status “Shut-off ”.

System parameter: Monitoring

Function no. 4401
Description The monitoring of short circuit/overload and undervoltage for the MSE6-E2M
can be activated or deactivated (suppressed). Active monitoring causes the
following. An error registered by the module will be:
– Sent to the higher-order fieldbus master
– Entered, if applicable, in the diagnostic memory (depending on filter settings)
– Entered in the module diagnostic data and, if applicable, in the status bits
– Displayed by the module common error LED
– Displayed by the red SF LED on the node.

System parameter: Fail safe (reaction to communication errors)

Function no. 4402
Description Specifies which signal status the outputs/actuators are to assume in the event
of fieldbus communication errors, e.g. in the event of:
– Communication failure (bus interruption, PLC/IPC failure)
– Communication stop.
In the following case, the channel-orientated Fail safe settings (module paramet-
ers Error mode and Error state) are reset automatically for safety reasons in
order to avoid undesired signal states:
– When changing from “Assume fault mode” to “Reset all outputs” or to “Hold
last state”.
Bit Bit 0, 1
Values Fail safe [Fail safe]
Bit 1 0 Description
0 0 Reset all outputs (presetting) [Reset outputs]
0 1 Hold last state (retain signal status) [Hold last state]

Comment The Fault mode status is set with the channel-specific module parameters. Addi-
tional information on this parameter can be found in section D.1.
Tab. C.5 Fail safe
System parameter: Force mode

Function no. 4402
Description Specifies for the MSE6-E2M whether the Force function is blocked or enabled.
By changing this parameter, the channel-orientated Force settings (module para-
meters Force mode and Force state) are reset automatically for safety reasons in
the following cases in order to avoid undesired signal states:
– Change via operator unit: When changed from “Enabled” to “Blocked”.
– Change via fieldbus: When changed from “Enabled” to “Blocked”.
Bit Bit 2, 3

Bit 3 2 Description
0 0 Blocked (presetting) [Disabled]
0 1 Enabled [Enabled]
Comment Force signals have precedence over Fail safe signals.

Function no. 4402
Description With this parameter, you can determine the start-up reaction of the MSE6-E2M
and save all current parameter settings and the current expansion.
Bit Bit 6
Values System start [System start]
Bit 6 Description
0 System start with default parameterisation (factory [Default parameters]
setting) and current expansion; external parameterisa-
tion is possible (presetting)
1 System start with stored parameterisation and stored [Saved parameters]
expansion; parameter and expansion are stored re-
manently; external parameterisation is blocked; the
M-LED on the fieldbus module is lit
Comment If bit 6 is set to 1, the current parameter settings will be “frozen” (write-protec-
ted) and the current expansion will be saved, except for bit 6 itself and the mod-
ule parameter “Force channel X”.
Recommendation: Select “System start with default parameterisation and cur-
rent CPX equipment status”. The desired parameterisation can then be created
in the start-up phase or after fieldbus interruptions e.g. by the interface module
or the scanner/bus master (depending on the fieldbus used). If “System start
with default parameterisation and current CPX equipment status” is active, the
factory settings for all module and system parameters will become valid after
Power On.

D Fundamentals of parameterisation
D.1 Influencing signal states

You can influence the signal states of the MSE6-E2M through the following functions:
Function Priority Brief description Signals able to
be influenced
Force 2) 1 Influences signal states independently of actual I/O signals
signal states ( Section D.1.1)
Fail safe 2 Specifies signal states, which take effect in the A signals
case of fieldbus communication errors
( Section D.1.2)
1) Only relevant for certain fieldbus protocols
2) Mainly used for test purposes in the commissioning phase.
Tab. D.1 Functions for influencing signal states
If several functions are active at the same time, the following applies:
– Force signals have the highest priority
Overview on the Force, Failsafe functions

Influencing output signals
With system parameters, you enter the fundamental settings for the respective function. With appropri-
ate setting of the system parameter, you can specify, through channel-specific module parameters, the
desired signal status for each channel individually. The following diagrams give an overview of this:

Forcing an input does not modify the input signal itself. The logical status of the input only changes
internally and may be effective in a program.
Obtain further information on Fail safe and Force from the following sections.
D.1.1 Force
Fundamentals
The function Force permits the manipulation of signal states independently of actual operating condi-
tions. Force enables input and output signals to be overwritten. Input signals actually present or
changes in status by the program will be ignored. The input signals actually present and the output
signals generated by the user program only become valid again when the Force function is deactivated.
Warning
Depending on the functions of the machine/system, the manipulation of signal states
can cause serious injury to human beings and damage to property.
Use the Force function very carefully, in order to avoid damage.
The “Force” function is used mainly in the commissioning phase in order to set certain signals to the
desired status for test purposes even if the wiring is not complete.

Parameterisation
With MSE6-E2M, Force parameterisation can be used for:
– Inputs of the I/O diagnostic interface and status bits
– Outputs of the I/O diagnostic interface and status bits
By means of a system parameter, Force is enabled globally for the MSE6-E2M or blocked.
System parameters Settings Description
Force mode Blocked Force is blocked for the complete MSE6-E2M

D.1.2 Signal status in the event of an error (fail safe)
Fundamentals
With the aid of the so-called fail safe parameterisation, the signal status, which the outputs are to as-
sume in the event of fieldbus communication errors, can be determined (fail safe status). In this way, a
defined machine/system status should be created in the event of fieldbus communication errors (e.g.
failure of the higher-order PLC/IPC).
Warning
Depending on the functions of the machine/system, the manipulation of signal states
can cause serious injury to human beings and damage to property.
Use the fail safe parameterisation very carefully, in order to avoid damage.
Parameterisation
With the MSE6-E2M, fail safe parameterisation can be used for:
– Digital outputs
– Analogue outputs.
By means of the system parameter Fail safe, you can globally determine the signal status which the
outputs/valves are to assume in the event of fieldbus communication errors, e.g. in the event of:
– Communication failure (fieldbus interruption, PLC failure)
– Communication stop.
System parameters Settings Description
Fail safe Reset outputs Reset all outputs, shut-off valve switches to the
(Presetting) “Pressurise” state
Hold last state Retain current signal status for all outputs
Assume Fault mode Accept the signal status defined for the relevant
value channel
Tab. D.4 System parameter “Fail safe”
D.2 Diagnostic memory
Fundamentals
A diagnostic memory serves for logging error states. Recording the time when errors occur and error
sequences facilitates the search for the cause of the errors which are otherwise difficult to locate. If the
causes are eliminated, errors can be avoided in the long term.

Parameterisation
Various diagnostic memory filters can be parameterised by means of diagnostic memory parameters
( Section 4.2.2). With these filters, the recording of certain system states can be suppressed, and
both starting and stopping can be controlled. The mode of operation of the diagnostic memory filters is
shown in Fig. D.5.
Start: Error
Run/stop filter 1 The first 40 errors or the last 40 errors
End of error filter Record end of error or not
Error number filter Record defined error number or not
Module/channel filter Record only error number of a module/channel
Run/Stop
Filter 2
0 = Always record
1 = Record up to the defined error number
2 = Record up to the defined error number + module number

Diagnostic
memory
3 = Record up to the defined error number + module number +

channel number
4 = Record as from the defined error number
5 = Record as from the defined error number + module number

6 = Record as from the defined error number + module
number + channel number
MN = module number, CN = channel number, FN = error number
Fig. D.5 The mode of operation of the diagnostic memory filters

Mode of operation
With the MSE6-E2M, the start and end of an error can be logged in the internal diagnostic memory. The
diagnostic memory contains up to 40 entries. In addition to information on localising the error, the rel-
evant time point is saved, measured from the moment the power supply is switched on. A diagnostic
entry consists of 10 bytes. The first 5 bytes contain information on the time. The last five bytes contain
information on the error ( Section C.3).
With the aid of the function number, entries in the diagnostic memory can be read out via
the I/O diagnostic interface, irrespective of the fieldbus protocol used. The various field-
bus protocols provide, where applicable, further possibilities for reading out and config-
uring the CPX diagnostic memory ( Description of CPX bus node).
D.3 Monitoring errors
Fundamentals
Monitoring functions that run automatically can be activated and deactivated by parameterisation.
The activation of monitoring functions helps to guarantee the functionality of the machine/system and
to avoid unnecessary idle periods. The deactivation of monitoring functions helps to avoid disturbing
error messages, e.g.:
– During commissioning
– During an EMERGENCY OFF, if the EMERGENCY OFF concept of the machine/system requires that
the load voltage for the valves and output modules be switched off. The error messages (e.g. under-
voltage), which are triggered when the load voltage is switched off, should be frequently sup-
pressed here.
Parameterisation
The MSE6-E2M permits the monitoring of various types of fault (e.g. limit monitoring, undervoltage,
etc.). The different monitoring functions can be activated or deactivated globally by system parameters
for the complete MSE6-E2M and by module parameters for a single module or an individual channel.
Activation of a monitoring function causes the following:
Monitoring Behaviour on activation
Module parameters An error on the module will be:
Monitoring – Passed on to the fieldbus node
– Displayed by the module common error LED
System parameters An error registered by the module will be:
Monitoring – Sent to the higher-order fieldbus master
– Displayed by the red SF-LED on the fieldbus node
– Entered in the module diagnostic data and, if applicable, in the status bits
– Entered, if applicable, in the diagnostic memory
Tab. D.5 Monitoring

The following monitoring functions can be activated or deactivated globally:
