Hello,
A new process line is being installed, it has its own safety PLC monitoring various E Stops / Guard switches etc...
Within the line is a piece of OEM equipment that has its own safety PLC, with its own E stops and guard switches etc..
Any E stop operated anywhere should inhibit the movement of everything on the line.
Only 1 reset PB is permitted.
I can see this would work using a time delay output from the master safety PLC to give an input to the slave safety plc, which will in turn give a reset enable input back to the master. But that all seems rather clunky
I've been having a think and cant really come up with a solution that doesn't require a timer somewhere..
Has anyone got any pointers or done anything similar?
kind regards
UKB
