Hello All
I need help, I am very new to the PLC world, we are experiencing some difficulty on a project. When ever take power away from a PLC box we sparious activation of valves causing unexpected actions.
Question:
Do PLC have a default setting, that when power is loss for a period of, power being unstable, that cause the PLC to drive a valve open?
This problem has occur when we power back up after an extended down period.
We dont perform a power sequence, we just cut the power. When we bring power back on line this when the problem occurs.
