4.2 Interface signals of the PLC application interface
General In the following list of interface signals, a reference to relevant documentation is

provided for every signal.
This reference specifies the section number or the short designation of the
description of functions, please refer to
References: /FB/, xx, ”yyy”
xx Short designation of individual description of functions (e.g.: /A2/)
yyy Name of description of functions (e.g.: ”Various interface signals”
or title of the guide)
Inverse signals Signals marked with a ”*” are so-called inverse signals. These signals initiate
the appropriate function when a 0 signal appears rather than a 1 signal (e.g.
MCP, byte n+2.0: *NC STOP).
• In STEP7, DBB means data module byte

Legend
• In STEP7, DBW means data module word (16 bits)
• In STEP7, DBD means data module double word (32 bits)

Note
With the SINUMERIK 840D, the machine control panel is assigned to the
input/output area by GP parameters; as a standard, initial address 0 is
specified for the input and output areas.
With FM-NC, the initial address is set via the SDB 210. For the supplied SDB
210, initial address 120 is specified. If another initial address is desired, this
must be specified via the STEP 7 Package Communication Configuration.
Note that the GD parameters given automatically through Communication
Configuration must be set on the machine control panel.

Note
With the SINUMERIK 840D, the handheld unit is connected to the OPI or
MCP interface of the PLC.
The initial addresses of the input/output areas and the activation must be set
via basic program parameter FB1. With the SINUMERIK 810D and FM-NC,
the handheld unit is connected to the MPI interface of the PLC.
The initial addresses of the input/output areas as well as the number of bytes
to be transferred must be specified via the STEP 7 Package Communication
Configuration.
Note that the GD parameters given automatically through Communication

Configuration must be set on the handheld unit.
The parameterization is described in the Installation and Start-Up Guide and

in the Description of Functions P3 ”Basic PLC program”.

Note
In DB2, the assignment is made between message/alarm number, text and

area identifier. All alarm or message bits are automatically transferred to the
user interface (channel, axis/spindle) through appropriate parameter settings.
If these parameter settings are not made, the bit transfer must be
programmed in the user program. The user interface can be further
influenced after the block for the error/operational messages has been called.
Only signals of the channels and axes declared in the NC machine data can
be transferred and texts displayed.
The user must acknowledge all error messages generated. Operational
messages are displayed only for as long as the relevant condition prevails.
The number of user areas can be parameterized via FB 1.
DB2/DB3 must be deleted after changing the configuration (FB1: MsgUser).

Note
#) Bits 4-7 of the digital input and NCK outputs can be processed by the PLC
even though there are no hardware I/Os available for this. Therefore, these
bits can be used in addition to the information exchange between NCK and
PLC.
§) On the 840D, the digital inputs and outputs 1 to 4 of the NCK are physically
on-board. On the FM-NC, there are no hardware I/Os for bit 0 to bit 3. These
can be processed by the PLC according to #).
The external I/O signals from the NCK have been shifted to the range starting
with DBB122.

Note
#) Although no associated hardware I/Os exist, the PLC can process bits 4-7
of the digital inputs and NCK outputs. Consequently, these bits can also be
used to transfer information between the NCK and the PLC.
§) The digital inputs and outputs 1 to 4 of the NCK exist as on-board

hardware for the 840D. No hardware I/Os are available for bits 0-3 of the FM-
NC. In accordance with #), these can be processed by the PLC.

Note
Concerning NCK CPU Ready (DBX 104.7):
This signal is the sign-of-life monitoring function for the NC. It must be
included in the safety circuit of the machine.
Concerning MMC CPU1 READY (DBX 108.3 and DBX 108.2):
If the MMC is connected to the operator panel interface (X 101), bit 3 is set
(default). When connecting to the PG MPI interface (X 122), bit 2 is set.

The initial and end addresses of the PLC machine data areas depend on the

DBD 136 DL function (REAL)
Note
With active tool management, programmed T functions are not output to the
PLC.
8-decade T nos. are only available as T function 1
Programmed D functions with names (e.g. D=CUTEDGE_1) cannot be
output in ASCII format to the PLC.
5-decade D nos. are only available as D function 1
The REAL format corresponds to floating point representation in STEP 7
(24 bit mantissa and 8 bit exponent). This floating point format supplies a
maximum of 7 valid places.

DBD 142 H function 1 (REAL or Dint) /H2/
DBW 158 Extended address F function 1 (binary) /H2/
DBD 160 F function 1 (REAL format) /H2/
Note
F functions are programmed in the part program in the REAL format.
The extended address of the F function contains an identifier with the
following meaning:
0 = path feed,
1-31 = machine axis number for feed with positioning axes.
The H function data type is dependent on MD 22110: AUXFU_H_TYPE_INT.

Note
M functions marked with * are not decoded in this bit array if a spindle is
configured in the channel. In this case, these M functions are offered as
extended M functions in DB21-30.DBB68 ff. and in the relevant axis DB
DB31-61.DBB86 ff.
Dynamic M functions (M00 to M99) are decoded by the basic PLC program.
The PLC user must use dynamic M functions in order to generate static M
functions.

DBB 270 Number of active G function of G function group n-1 (binary) /K1/
DBB 271 Number of active G function of G function group n (binary) /K1/
Note
The active G functions of the groups are updated each time a G function or a
mnemonic identifier (e.g. SPLINE) is programmed.
G functions within a G group are output as binary value, starting with 1.
A G function with the value 0 means that no G function is active for this G
group.
