5.2.2
Configuring a Non-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
Remove the comment parentheses from the
COM block.
4
Use parameter L1M to enter the station num-
ber of the L2 station for which the non-safe-
ty-related connection is to be installed.
5
Clear parameter PRI and dummy characters
"..." or enter the priority list.
6
Write the modified DB1 into the CP 541.
7
Switch the CP 541 to RUN.

You need this chapter to set up a non-safety-related PLC-PLC connection
from an S5-115F.
You install the non-safety-related PLC-PLC connection with the S5-95F as
shown in Section 4.1.
You assign parameters for the non-safety-related PLC-PLC connection via
the CP 541 as shown in the following table.
Action
You must observe the following points in the connected PLC:
The station number set in the CP 541 must be identical to the node ad-
dress of the connected programmable controller.
The non-safety-related PLC-PLC connection can contain up to 64 bytes of
data.
CP 541 with S5-95F/S5-1 15F
Remark
–
The station number of the CP 541 must be
identical to the node address of the con-
nected PLC.
For the change in the COM block to be ef-
fective, you must remove the comment pa-
rentheses.
The S5-115F can only set up a non-safety-re-
lated connection for node address 0 (SINEC
L1 master). This address is reserved in
SINEC L2.
The CP 541 will convert the address to the
station number specified with parameter
L1M.
The CP 541 cannot start with the dummy
characters for the priority list in DB1.
–
Only upon transition from STOP to RUN
will the modified DB1 be stored in the EE-
PROM of the CP 541.
