If I connect a 4-20mA output from say a magnetic flowmeter (4-wire device) to a PLC AI module (CompactLogix) and to a digital display on the door in a loop and the PLC loses power will the digital display on the door read whatever value corresponds to 0.0mA?
i.e.: Does the loop get broken when the PLC AI module is no longer powered?
Thanks all.
