Hi experts
I have question, (may be it is stupid question)
For SAFETY PLC where we define the which SAFE state it has attain?
I mean what exactly happens when SAFTEY PLC finds the input circuit is faulty?
with example, for some valves OPEN state is FAIL SAFE, for some it is CLOSE. in case of MCC contacts OPEN contact.
so these state to be defined in the SAFETY Program??
i did lot research to find and read lot papers, but...... HELP
Thanks
