12.7 Transmission of Safe Signals over Several Machines or Machine Parts

There are several ways of exchanging safe signals between different PLCs using SCP111.

According to topology there is the following distinction:

•

Connection via VBC021 (requires a VaranManager on both PLCs)

Connection via VMC052 (requires a VaranManager on the higher-level PLC, the lower-level
PLC must be a C-IPC with VMC052 plug-in card)
