H-12
The example here shows a safety-related PLC-PLC connection between two
failsafe programmable controllers: the S5-95F and S5-115F.
With a positive-going edge at I 32.0, the value of IB 33 is sent from each
PLC (S5-95F and S5-115F) to the partner PLC, and indicated there at QB 32.
Shown in Figure H-3 is the configuration for the safety-related PLC-PLC
connection between an S5-95F and an S5-115F.
Note that the CP 541 is connected to part-PLC B at both programmable con-
trollers.
