3.3.1 Installation instructions for devices without a diaphragm seal –

PMC41, PMC45, PMP41, PMP45
! Note!
• If a heated Cerabar M is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time, whereby moisture can penetrate the sensor through the pressure compensation
➀. If this is the case, mount the Cerabar M with the pressure compensation ➀ pointing
downwards.
➀
➀
• Keep the pressure compensation and GORE-TEX filter ➀ free from dirt.
®
• Cerabar M devices without diaphragm seals are mounted as per the norms for a manometer
(DIN EN 839-2). We recommend the use of shutoff devices and siphons. The orientation depends
on the measuring application.
• Do not clean or press the diaphragm with hard or pointed objects.

3.3.2 Installation instructions for devices with diaphragm seals –

PMP46, PMP48
! Note!
• The Cerabar M with a diaphragm seal is screwed in, flanged or clamped, depending on the type
of diaphragm seal.
• Together, a diaphragm seal and the pressure transmitter form a closed, calibrated system which
is filled with oil. The filling hole is sealed and should not be opened.
• Do not clean or press the diaphragm of the diaphragm seals with hard or pointed objects.
• Do not remove diaphragm protection until shortly before installation.
• When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in order
to prevent the capillary from buckling (bending radius ≥ 100 mm).
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero
point shift. The position-dependent zero point shift can be corrected directly at the device via
2 keys → see Page 44, Section 7.3.8 "Position adjustment - only display (bias pressure)" (onsite
operation) or via communication → see Page 45, Section 7.3.9 "Zero point correction".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Cerabar M TI399P, "Planning instructions for diaphragm seal systems" section.
In order to obtain more precise measurement results and to avoid a defect in the device, mount the
capillaries as follows:
• Vibration-free (in order to avoid additional pressure fluctuations)
• Not in the vicinity of heating or cooling pipes
Insulate if the ambient temperature is below or above the reference temperature
• With a bending radius of ≥ 100 mm.
14 Endress+Hauser
Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter
below the diaphragm seal. This prevents a vacuum load of the diaphragm seal caused by the
presence of filling oil in the capillaries.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 - as illustrated in the diagram below left - must not be exceeded. The maximum
height difference depends on the density of the filling oil and the lowest pressure that is permitted
to occur at the diaphragm seal (empty tank), see the following illustration.

Mounting with temperature isolator
max. 115
P01-PMP4xxxx-11-xx-xx-xx-006
Endress+Hauser recommends the use of temperature isolators in the event of constant extreme fluid
temperatures which lead to the maximum permissible electronics temperature of +85°C (+185°F)
being exceeded. To minimize the influence of rising heat, Endress+Hauser recommends the device
be mounted horizontally or with the housing pointing downwards.
The additional installation height also brings about a zero point shift of approx. 21 mbar due to the
hydrostatic column in the temperature isolator. The position-dependent zero point shift can be
corrected directly at the device using 2 keys → see Page 44, Section 7.3.8 "Position adjustment -
only display (bias pressure)" (onsite operation) or via communication → see Page 45, Section 7.3.9
"Zero point correction".

Mounting with capillary tube

The housing of the Cerabar M can be mounted with a capillary tube to one side of the measuring
point to protect from high temperatures, moisture or vibration, or in cases where the mounting
point is not easily accessible.
A bracket for mounting on a wall or pipe is available for this purpose.

Cerabar M mit PROFIBUS PA Wiring
4 Wiring
4.1 Electrical connection

! Note!
Cerabar M with a PROFIBUS-PA output is a two-wire transmitter. Note the following before
connecting the device:
• Turn off the power supply.
• Ground the device using the external ground terminal.
4.1.1 Power supply

The Cerabar M has the following connection values:
I = 11 mA ± 1 mA
Non-hazardous area: U = 9 to 32 V DC
Hazardous area: U = 9 to 24 V DC
4.1.2 Bus cable

Endress+Hauser recommends you use a twisted, shielded twin-core cable. The following values
must be observed for installation in Ex areas (EN 50020, FISCO model):
Loop-resistance (DC): 15 to 150 W/km

Inductance per unit length: 0.4 to 1 mH/km
Capacitance per unit length: 80 to 200 nF/km
The following are examples of suitable cable types:
Non-hazardous area:
• Siemens 6XV1 830-5BH10 (gray)

• Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL (gray)
• Belden 3076F (orange)
Hazardous area:
• Siemens 6XV1 830-5AH10 (blue)
• Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL (blue)
4.1.3 Shielding
For maximum EMC protection, e.g. near frequency convertors, it is advisable to connect the
housing and cable shielding using a potential matching line (PML). (Max. wire cross-section:
2.5 mm², fixed conductor)
Please pay attention to the following points:
• Ground the device using the external ground terminal.

• The bus cable shield may not be interrupted.
• Ground the shield at each end of the cable, and always try to keep the connecting cable between
the shielding and ground as short as possible.
• If there are large potential differences between the individual grounding points, you only need to
connect one point to the reference ground. Connect all the other ends of the shield via a
HF-enabled capacitor with reference potential (e.g. ceramic capacitor 10 nF/250 V~).
Endress+Hauser 19

6.2 Device address configuration

An address must be assigned to every PROFIBUS-PA device. If the address is not set correctly, the
device will not be recognized by the process control system.
• Valid device addresses are in the range from 0 to 126. All devices are delivered with the software
address 126 on leaving the factory.
• A device address may appear only once within a particular PROFIBUS-PA network. Please refer
also to the Operating Instructions BA198F for further information.
Endress+Hauser 27
PROFIBUS-PA interface Cerabar M mit PROFIBUS PA
The address 126 set at the factory can be used to check the function of the device and to connect
to a PROFIBUS-PA network already in operation. Afterwards the address should be changed to
allow other devices to be connected to the network.
There are two ways of assigning an address to a Cerabar M:
• With software using an operating program, (DP Class 2 master e.g. Communwin II or
• Locally via DIP switches. The DIP switches are located on the electronic insert.

6.2.3 Software addressing

Please refer to Operating Instructions BA198F for the procedure for addressing devices via software.
6.3 Device master and type files (GSD)

A device master file (GSD) contains a description of the properties of a PROFIBUS-PA device, e.g.
what data transmission rate the device supports or what digital information the PLC gets from the
device and in what format. Bitmap files also belong to the GSD files. These allow the measuring
points to be represented as a graphic. The device master file and corresponding bitmaps are required
to plan the PROFIBUS-DP network.
28 Endress+Hauser
Every device is allocated an ID number by the PROFIBUS User Organization (PNO). The name of
the device master file (GSD) is derived from this. For Endress+Hauser, this ID number always starts
with "15XX", where "XX" stands for the device name.

– PNO È http://www.de.PROFIBUS.com (GSD library)
• CD-ROM
– Directly from Endress+Hauser: order no. 56003894
! Note!
The PNO provides a universal database file called PA_x9700.gsd for devices with one Analog
Output Block. This file supports the transmission of the primary measured value. This database file
does not support the transmission of a second measured value (2nd cyclic value) or a display value
(Display value). The universal profile must be selected via matrix field V6H0 in Commuwin II.
6.3.1 Working with GSD files

The GSD files must be loaded into a specific subdirectory in the PROFIBUS-DP network design
software of your PLC.
• GSD files and bitmaps that are located in the "Extended" directory are used, for example, for the
configuration software STEP7 of the Siemens S7-300/400 PLC family.
• x.200 files and bitmaps that are located in the "Typdat5x" directory are used for the configuration
software COM ET200 with Siemens S5.
• GSD files that are located in the "Standard" directory
are for PLCs that support the "identifier byte" (0x94) but not the "identifier format". They can be
used with an Allen-Bradley PLC5, for example.
More details about the directories used for storing the GSD files can be found in the Operating
Instructions BA198F.

The values in brackets indicate the matrix position in the operating program.
6.4.1 Block model

The block model of a Cerabar M is shown in → Fig. 25. The primary measured value V0H0 is
transferred from the Transducer Block to the Analog Input Block. Here, the measured value is scaled
and limit values added before being output to the PLC as the variable OUT during cyclic data
communication. A value and the related status is transmitted with the variable OUT.
The onsite display and the matrix field V0H0 normally show the same value. However, a cyclic
output value (Display value) can also be made available to the onsite display via a PLC. For this, the
matrix field V6H5 in Commuwin II must be set to "Display Value" or "1". Example: Two Cerabar
M transmitters measure the pressure drop across a filter. The differential pressure is registered in
the PLC and then allocated to the matrix field V6H6.
A Cerabar M can output a secondary value to the PLC. A value can be selected via the field V6H4
in Commuwin II.
6.4.2 Configuration
The data exchange must be configured via a network design tool and a operating program.
1. Use the network design tool for your PLC and add the Cerabar M to the network. Ensure that
the address assigned corresponds to the set device address.
2. Select Cerabar M and start the configuration program. Four options appear: "Main process
value", "2nd cyclic value", "Display value" and "FREE PLACE".
3. Select "Main process value". If no other values are required, close the configuration window,
otherwise
4. Select "2nd cyclic value" or "FREE PLACE" (= function disabled) and select "Display value" or
"FREE PLACE" (= function disabled). Then close the configuration window.
5. Start operating program and establish the connection to the bus using the server PA-DPV1
(Commuwin II) or PROFIdtmDPV1 (FieldCare). Then generate a live list, locate the device
address and click Cerabar M.
6. Open the device menu. Select the operating matrix (Commuwin II only).
7. If required, select a secondary measured value via the matrix field V6H4:
30 Endress+Hauser
0 = Sensor value, 1 = Trimmed value, 2 = Biased value.

8. To display a cyclic output value (Display value) on the onsite display, set V6H5 = "Display
value" (or "1").
9. The data exchange is now configured for this Cerabar M.
6.4.3 Cerabar M È PLC (input data)

With the Data_Exchange service, a PLC can read the input data from a Cerabar M in the response
telegram. The cyclic data telegram has the following structure.

6.6 Data format
6.6.1 IEEE 754 format

The measured value is transmitted as an IEEE -754 floating point number, whereby:
Measured value = (-1)sign x 2(E - 127) x (1+F)
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Sign Exponent (E) Fraction (F)

Example
40 F0 00 00 hex = 0100 0000 1111 0000 0000 0000 0000 0000 binary
Value = (-1)0 x 2 (129-127) x (1 + 2-1 x 2-2 x 2-3)

= 1 x 22 x (1 + 0.5 x 0.25 x 0.125)
= 1 x 4 x 1.875
= 7.5
! Note!
• Not all PLCs support the IEEE 754 format. If this is the case, a conversion module must be used
or written.
• Depending on the type of data storage used in the PLC (master) - (most significant
byte or low significant byte) - the byte sequence might have to be altered (byte swapping routine).
6.6.2 Data strings

Some data types, e.g. DS-36, are marked with an asterisk in the slot/index table (→ see Page 33,
Section 6.5.1 "Slot/index table"). These data types are data strings that are structured according to
the PROFIBUS-PA Specification Part 1, Version 3.0. They comprise several elements that are
addressed via the slot, index and subindices, as shown in the following two examples:
Parameter Slot Index Element Subindex Type Size

DS-36 27 OUT Scale Max. 1 FLOAT 4
OUT Scale Min. 5 FLOAT 4
OUT Scale Unit. 9 UNSIGNED16 2

OUT Scale DP 11 INTEGER8 1
(decimal point.)
6.7 Configuration of parameter profiles

You can access the block parameters via a PROFIBUS-DP Class 2 master, such as Commuwin II/
FieldCare. Commuwin II/FieldCare runs on an IBM-compatible computer or laptop. The computer
must be equipped with a PROFIBUS interface, i.e. PROFIBOARD for PCs and PROFICARD for
laptops. During the system integration, the computer is registered as a Class 2 master.
6.7.1 Operation via FieldCare

The operating of FieldCare are described in the integrated FieldCare online help.
The PROFIdtmDPV1 server has to be installed for operation.
6.7.2 Operation via Commuwin II

The PA-DPV1 server has to be installed for operation. Then establish the connection to
Commuwin II via this server.
• Generate a live list with "tags".
• Select the E+H device operation by clicking the device name, e.g. Cerabar M.
• Select profile operation by clicking the appropriate tag, e.g. AI: PIC 209 = Analog Input Block
Cerabar M or by selecting the related device profile in graphic operation.
• The settings are then entered in the "Device parameter" menu.
Device parameter menu

The "Device parameter" menu in Commuwin II offers you two operating modes, namely "Matrix
operation" and "Graphic operation".
• During matrix operation, the device or profile parameters are loaded to a matrix. A parameter can
be changed when the corresponding matrix field is selected.
• In the case of graphic operation, the operating sequence is shown in a series of graphics with
parameters. For profile operation, the Diagnosis, Scaling, Simulation and Block graphics are of
interest.
Output scaling
The Cerabar M onsite display and the digital output operate completely independently of each
other. As standard, the output value (OUT value) is transmitted in the unit specified on the
nameplate.
38 Endress+Hauser
Digital output value (Out value) = display value of the onsite display
The following operating options are available so that the display and the digital output produce the
same value:
• Set the values for the lower and upper limit of PV scale and OUT scale in the Analog Input Block
as equal; PV Scale min. = OUT Scale min. and PV Scale max. = OUT Scale max. See also (→ see
Page 33, Section 6.5.1 "Slot/index table") and Section 11.1 "Matrix for Analog Input Block (AI
Transmitter)",
• Scale the limits of PV scale and OUT scale in Commuwin II in the graphic mode, see illustration
below or
• Confirm the "Set unit to bus" parameter in accordance with Section 7.3, "Selecting a pressure
unit" section. Confirming this parameter automatically sets the PV scale and OUT scale limits to
the same value.
Digital output value (Out value) ≠ display value of the onsite display
If you require an output value for your PLC that is scaled differently than the display value on the
onsite display, the following operating options are available:
• Set the values for the lower and upper limit for PV scale and OUT scale in the Analog Input Block
as per the requirements, (→ see Page 33, Section 6.5.1 "Slot/index table") and Section 11.1
"Matrix for Analog Input Block (AI Transmitter)" or
• Scale the limits of PV scale and OUT scale in Commuwin II in the graphic mode, see illustration
below.
! Note!
If you wish to perform position adjustment using bias pressure for the value indicated on the onsite
display (see Section 7.3 "Position adjustment - only display (bias pressure)") this must be done before
changing the values for OUT scale min. and OUT scale max.

Commissioning Cerabar M mit PROFIBUS PA
7 Commissioning
The Cerabar M is ready for measurement immediately. The measuring range corresponds to the
information on the nameplate. As standard, the pressure applied is transmitted via PROFIBUS-PA
in the unit specified on the nameplate. The measured value is transmitted in the unit "bar" following
a "5140" reset in the V2H9 matrix field (→ see Page 50, Section 9.5 "Reset").
There is no turndown in the conventional sense for PROFIBUS-PA digital signal transmission. The
measured value is transmitted with a resolution corresponding to an accuracy of 0.2 %.
7.1 Function check

Carry out a post-installation and a post-connection check as per the checklist before commissioning
the device.
• "Post-installation check" checklist (→ see Page 18, Section 3.4 "Post-installation check")
• "Post-connection check" checklist (→ see Page 23, Section 4.5 "Post-connection check")
7.2 Onsite commissioning
7.2.1 Preparatory work

can be output on the onsite display.
7.2.3 Upper-range value calibration

Calibration of the upper-range value is carried out using the "Span" key.
Proceed as follows when calibrating the upper-range value:
• Specify the exact pressure for the upper-range value.
• Press the Span key twice.
The acting pressure is adopted as the upper-range value.
By pressing the Span key once the value saved as the upper-range value
can be output on the onsite display.
7.3 Commissioning and operation
7.3.1 Preparatory work

Connect the Cerabar M, see Section 4.1Electrical connection.

! Note!
As standard, the measured value is transferred via the bus in the pressure unit given on the
nameplate. For the digital output value and the measured value in the matrix field V0H0 to display
the same value - even after selecting a new pressure unit - you must confirm the "Set unit to bus"
parameter in V6H1 once. Note that a change of the digital output value can influence the controller.

7.3.9 Zero point correction

The "Zero offset" (V9H5) parameter offers a further possibility of carrying out position adjustment.
In contrast to position adjustment using bias pressure (V0H5/V0H6), the digital output value (OUT
value) is also corrected in addition to the display value on the onsite display (measured value
(V0H0)). When carrying out a zero offset, an applied pressure is assigned a correction value via "Zero
offset" (V9H5). This shifts the sensor characteristic curve according to the diagram and the "Low
sensor cal" (V7H4) and "High sensor cal" (V7H5) values are recalculated. The "Zero offset value"
(V9H6) matrix field indicates the value by which the sensor characteristic curve was shifted.
The value is calculated as follows for "Zero offset value" (V9H6):
• Zero offset value (V9H6) = Sensor pressure (V7H8) - Zero offset (V9H5)
The "Sensor pressure" (V7H8) displays the pressure currently applied.

9.4 Simulation (Commuwin II only)

You have the option of simulating either the output value (OUT value) or the function of the Analog
Input Block. In the following sections, the matrix fields in brackets indicate the matrix position in
the Analog Input Block display in the operating program. See also Section 11.1 "Matrix for Analog
Input Block (AI Transmitter)".
9.4.1 OUT value simulation

You can simulate the output value (OUT value) as follows:
1. Where necessary, unlock the matrix using code 130 or 2457 in matrix field VAH9.
2. Using matrix field V9H9, switch from the standard to the Analog Input Block display.
3. Set the mode of the "Target mode" parameter (V8H0) to "manual".
– You can now enter a simulation value directly for the "OUT value" (V0H0).
– Afterwards, check the change to the OUT value, e.g. at the PLC.
4. Set the "Target mode" parameter back to "automatic".
! Note!
The operating program offers a further option of specifying an OUT value using the graphic
operation in the "Simulation AI-Block" menu.
9.4.2 Analog Input Block simulation

You can simulate the function of the Analog Input Block as follows:
1. Where necessary, unlock the matrix using code 130 or 2457 in matrix field V9H9.
2. Using matrix field VAH9, switch from the standard to the Analog Input Block
display.
3. Set the "Simulation" parameter in the Analog Input Block (V7H2) to "on".
– You can now enter a simulation value directly for "Simulation value" (V7H0).
– Afterwards, check the change to the OUT value (V0H0) and at the PLC.
4. Set the "Simulation" parameter back to "off".

Other reset codes have the following effects:

• 2506: Device warm start
• 2509: This reset sets the lower and upper sensor calibration limits and the zero offset value to the
factory setting, i.e.:
Low sensor cal = low sensor limit (V7H4 = V7H6),
High sensor cal = high sensor limit (V7H5 = V7H7),
Zero offset value (V9H6) = 0.0
• 2712: The device address set via the bus is reset to the default value 126.

11.2 Description of parameters
Matrix field/ Description

parameter
Measured value This parameter indicates the value currently measured. V0H0 corresponds to the onsite display.
(V0H0) Select a pressure unit via the "Select pressure unit" (V0H9). The measured value is converted
and displayed in the pressure unit you selected.
Note: As standard, the measured value is transmitted via the bus in the pressure unit indicated
on the nameplate. To transmit the converted measured value via the bus, the
"Set unit to bus" must be confirmed once in the V6H1 matrix field/parameter.
See also Matrix/Parameter description for "Set unit to bus" (V6H1).
Lower-range value Enter a pressure value for the lower-range value (calibration without reference pressure).
(V0H1) Use this parameter to set the lower-range value for the bar graph on the onsite display.
This parameter has no effect on the digital output value (OUT value).
See Section 7.3, "Calibration without reference pressure".
Factory setting: 0.0
Upper-range value Enter a pressure value for the upper-range value (calibration without reference pressure).
(V0H2) Use this parameter to set the upper-range value for the bar graph on the onsite display.
This parameter has no effect on the digital output value (OUT value).
See Section 7.3, "Calibration without reference pressure".
Factory setting: "Upper range limit" (V7H7)
Endress+Hauser 55

parameter
Set lower value If you confirm this parameter, the current pressure value is set as the lower-range value
(V0H3) (calibration with reference pressure). The lower-range value only refers to the bar graph on the
onsite display. It has no effect on the digital output value (OUT value).
The value is displayed in the "Lower-range value" parameter (V0H1).
This is equivalent to pressing the Zero key twice during onsite operation.
Set upper value If you confirm this parameter, the current pressure value is set as the
(V0H4) upper-range value (calibration with reference pressure). The lower-range value
only refers to the bar graph on the onsite display. It has no effect on the
digital output value (OUT value).
The value is displayed in the "Upper-range value" parameter (V0H2).
This is equivalent to pressing the Span key twice during onsite operation.
Set bias pressure If the onsite display does not show zero after calibrating the lower-range value at zero operating
(V0H5) pressure (position-dependent), you can correct the display value of the onsite display to zero by
entering a pressure value (bias pressure)
(position adjustment). The "Measured value" (V0H0), "Lower-range value" (V0H1) and
"Upper-range value" (V0H2) parameters are corrected by the bias pressure.
Note: In the "Pressure" operating mode, position adjustment via a bias pressure
has no effect on the digital output value ("OUT value" parameter) which is
transmitted via the bus. For the onsite display and the "OUT value" (V6H2)
to display the same value, the "Set unit to bus" must be confirmed in
Matrix field/Parameter V6H1. See also Section 7.3, "Position adjustment - only display (bias
pressure)".
Bias pressure If you confirm this parameter, the current pressure value is adopted as the bias pressure.
autom. The value is displayed in the "Set bias pressure" (V0H5).
(V0H6) This is equivalent to pressing the Zero and Span key twice simultaneously during onsite
operation.
See also parameter description for "Set bias pressure" (V0H5).
Set output damping The damping (integration time) affects the speed at which the output signal and the
(V0H7) display value react to a change in the pressure.
Damping is adjustable from 0 to 40 s. Factory setting: 0.0
Select Select a pressure unit.

pressure unit If a new pressure unit is selected, all the pressure-specific parameters
(V0H9) are converted and displayed in the new pressure unit.
Note: As standard, the measured value is transmitted via the bus in the pressure unit
indicated on the nameplate. To transmit the converted measured value via the bus, the
"Set unit to bus" must be confirmed once in the V6H1 Matrix field/Parameter.
See also parameter description for "Set unit to bus" (V6H1).
See Section 7.3, "Selecting a pressure unit".
Factory setting: see information on the nameplate
Diagnostic code The pressure transmitter outputs an error code if it detects a fault or a warning.
(V2H0) This parameter indicates the current error code.
For a description of the error codes, see Section 9.3.
Last diagnostic Indicates the last error code.

parameter
Manufacturer ident. For selecting the ID number. Options:

number – Profile: General ID number of the PNO (PROFIBUS User Organization):
(V6H0) "9700 (hex)". To configure the PLC, the device master file (GSD) of the
PNO (Profibus User Organization) must be used.
– Manufacturer: Device ID number for Cerabar M PROFIBUS-PA: "151C (hex)".
To configure the PLC, the device-specific GSD must be used.
See also Section 6.3 "Device master and type files (GSD)".
Set unit In the following instances, the digital output value (OUT value) and the onsite display or the
to bus "Measured value" parameter (V0H0) do not show the same value:
(V6H1) – If you have selected a new pressure unit via the "Select pressure unit" (V0H9) and/or
– If you have performed position adjustment in the "Pressure" operating mode by entering a
bias pressure (V0H5/V0H6).
To make the digital output value display the same value as the onsite display or V0H0 in
such instances, the "Set unit to bus" in Matrix field/Parameter V6H1 must be confirmed
after calibration. Note that a change of the digital output value can influence the controller.
See also Section 7.3, "Selecting a pressure unit" and "Position adjustment - only display (bias
pressure)".
V6H2 This parameter shows the OUT value of the Analog Input Block (digital
OUT value output value that is transmitted via the bus).
(V6H2) As long as Matrix field/Parameter V6H2 continues to display UNKNOWN,
"Set unit to bus" in Matrix field/Parameter V6H1 has not yet been confirmed.
OUT status This parameter shows the status of the OUT value (digital output value).
(V6H3) For the description of the status codes, see Section 6.4, "Status codes".
2nd cycl. value This field can be used to select a second parameter that is output cyclically to the PLC.

parameter
Zero You can use this parameter to perform a calibration (zero point correction) simultaneously
offset for the display value of the onsite display ("Measured value" (V0H0)) and for the
(V9H5) digital output value (OUT value).
By entering a value for this parameter, you can assign a new value to a pressure
applied at the device. The sensor characteristic curve is shifted by this value and the
"Low sensor calibration" (V7H4) and "High sensor calibration" (V7H5) parameters are
recalculated.
See Section 7.3, "Zero point correction".
Zero Displays the value by which the sensor characteristic curve has been moved during zero
offset value point correction.
(V9H6) See also parameter description for "Zero offset"
(V9H5) and Section 7.3, "Zero point correction".
Unbiased pressure This parameter indicates the pressure currently present and damped without bias correction.
(V9H7) See also parameter description for "Set bias pressure" (V0H5).
Bias This parameter indicates the pressure currently present and damped after
pressure bias correction. See also parameter description for "Set bias pressure" (V0H5).
(V9H8) Calculation: "Bias pressure" (V9H8) = "Unbiased pressure" (V9H7) – "Set bias pressure" (V0H5)
In the "Pressure" operating mode, this parameter and the "Measured value" parameter
(V0H0) display the same value.
