Hi All,
I am implementing "analog interlocks" in a PID module using the AT block. I need to provide a status that indicates an interlock has caused the output state to change similar to the ILK_SHUTD_ACTIVE parameter for EDC block. Based on BoL and some experimentation , it looks like checking for a non zero FIRST_OUT parameter value and that the PID is in LO provides analogous indication but am not sure if this is right. Hoping for some experienced insight here.
Thanks!
