I am integrating a multirobot cell safety system with SafeOperation and safety via Profisafe to a S7-1511F PLC using Portal v15 to program it. The customer has requested that we display the SafeOps checksums on the cell HMI so that the plant safety officer can periodically monitor the system to see if the configurations have been modified. I told them I will see if it is possible.
I can't see anywhere in the PLC hardware config that shows the checksum nor in the F I/O DB that is associated with the robot device.
Failing that, is there a KRC4 system variable available for the SafeOps checksum that I could pass to the PLC for this purpose? I think the whole exercise is a bit dumb (just walk over and check the pendant), but they seem to want it, and if it's possible to do this way then it might be less work than convincing them that it is not necessary.
Thanks.
