Hi all,
I was wondering if anyone had any good methods for developing functional spec / test sheets for equipment interlocks.
I find the best method to describe a particular process / equipment interlock is the ladder logic itself.
I have also seen the method with defining signals: A = Tank High Level, B = Mains Phase Failure
Then expressing as: PMP005_INTERLOCK = A | B
Any ideas /comments would be awesome!
