– PG communication for uploading / downloading of S7 configuration, diagnostics and
routing
– Operator control and monitoring functions (HMI communication)
– Data exchange over S7 connections
●
Data record routing / field device parameter assignment
You can use the CM as a router for data records intended for field devices (DP slaves).
Data records from devices that are not connected directly to PROFIBUS and therefore
have no direct access to the DP slaves are forwarded to the DP slaves by the CM.
The services of the CM 1542-5 listed above can be used independently at the same time.
Note
Requirement for FDL, data record routing, loading of configuration/diagnostics data
For the functions FDL, data record routing and loading configuration and diagnostics data
the CM must either be operated in the mode DP master mode or as a DP slave with the
option "Test, Commissioning and Routing" enabled.

Time-of-day synchronization - time master or time slave
The CM 1542-5 can be enabled for time-of-day synchronization. As an alternative, the CM
can be configured as time master or time slave on PROFIBUS.
● Time master: The CM is synchronized using the time of day in the S7-1500 station and
outputs the time of day on PROFIBUS. The output interval can be set.
● Time slave: The CM receives time-of-day frames on PROFIBUS and outputs the time
within the S7-1500 station. The output interval within the S7-1500 station is set
permanently to 10 seconds.
Note
Recommendation for setting the time
It is advisable to set the time
-of-day master so that time-of-day frames are sent at interval
s of
approximately 10 seconds. This achieves as small a deviation as possible between the
internal time and the absolute time.
Web diagnostics
With the aid of Web diagnostics of the CPU, you read the diagnostics data from an S7
station via the Web browser on the PG/PC.
In terms of the CM, the Web pages provide the following information:
● Module and status information
● Special information on the DP master system (status of the DP slaves)

Note
PROFIBUS interface
The CM provides no 24
VDC power supply on the PROFIBUS interface. I/O devices (for
example, PC adapter 6ES7972
-0CB20-0XA0) are therefore not operational on the interface).
3.4
Mode of the CPU - effect on the CM
You can change the mode of the CPU between RUN and STOP using STEP 7 or the switch.
Depending on the operating status of the CPU, the CM behaves as described below.
Changing the CPU from STOP to RUN
● Programmed connections are established.
● In DP master mode:
– Change from CLEAR to the OPERATE mode
● In DP slave mode:
– Going diagnostics interrupt to the master
– Current input data is transferred.
Changing the CPU from RUN to STOP
The reaction is as follows in STOP:
● Programmed connections are terminated.
● In DP master mode:
Change to the CLEAR mode
● In DP slave mode:
– Input data is sent to the DP master with the value "0" and a DP diagnostics alarm is
sent.
● Regardless of the mode, the following functions remain enabled:
– The configuration and diagnostics of the CM
Relevant system connections for configuration, diagnostics and PG channel routing
still exist.
– Data record routing
– S7 routing function
– Time-of-day synchronization
– Configured connections remain established.

The program block can be found in STEP 7 in the "Instructions > Communication > Open
User Communication" window.
Connection description of the type "TCON_FDL"
To reference the connection description, the blocks "TCON" and "TSEND_C / TRCV_C" use
the CONNECT patrameter. The connection description is stored in a data block whose
structure is specified by the system data type (SDT) "TCON_FDL".
Creating an SDT for the data block
You create the SDT required for every connection description as a data block. You generate
the SDT type in STEP 7 by entering the name ("TCON_FDL") in the "Data type" box
manually in the declaration table of block instead of selecting an entry from the "Data type"
drop-down list. The SDT is then created with its preset parameters.
For FDL the following SDTs are used:
●
TCON_FDL
For transferring data via FDL
You will find the description of TCON_FDL in the STEP 7 information system (keyword
"TCON_FDL").
Programmed connection establishment or termination with TCON / TDISCON
Connections are established using the program block TCON. Note that a separate program
block TCON must be called for each connection.
A separate connection must be established for each communications partner even if
identical blocks of data are being sent.

terminated by calling "TDISCON".
Note
Connection abort
If an existing connection is aborted by the communications partner or due to disturbances on
the network, the connection must also be termi
nated by calling TDISCON. Make sure that
you take this into account in your programming.
Configured and programmed FDL connections

DP diagnostics frames when the CPU is in STOP
DP diagnostics frames when the CPU is in STOP
All diagnostics frames from DPV0 standard slaves and all DP interrupt frames from DP-
S7/DPV1 standard slaves arriving when the CPU is in STOP are forwarded to the CPU.
During module startup, the diagnostics frames must then be evaluated by a suitable user
program.
