CP 541 with S5-95F/S5-1 15F
5.2.1
Configuring a Safety-Related PLC-PLC Connection
Introduction
Assigning Parame-
ters to the CP 541
Step
1
Load DB1 into the programmer.
2
Enter the station number of the CP 541 with
parameter TLN in frame SL2.
3
Write the modified DB1 into the CP 541.
4
Switch the CP 541 to RUN.
In the
Programmable
Controller
5-6
The safety-related PLC-PLC connection is comparable to a point-to-point
connection between two failsafe programmable controllers.
You can easily install the safety-related PLC-PLC connection with the pa-
rameters stored in the default DB1.
You assign parameters for the safety-related PLC-PLC connection via the CP
541 as shown in the following table.
Action
In the connected programmable controller, you must observe the following
points when assigning parameters with COM 95F or COM 115F:
The station number set in the CP 541 must be identical to the node ad-
dress of the connected programmable controller.
You must use message mode 115F-15 to set up the connection.
You can access node addresses 1 to 30 with the connected programmable
controller.
Each message of the safety-related PLC-PLC connection can contain up
to 60 bytes of net data.
Remark
–
The station number of the CP 541 must be
identical to the node address of the con-
nected PLC.
–
Only upon transition from STOP to RUN
will the modified DB1 be stored in the
EEPROM of the CP 541.
