Hey
I was wondering if you guys could explain to me how the signal flows on a analog & digital signal.
for example:
Explain the wiring of a 2-wire, 24v, 4-20mA transmitter that measures pressure that goes back into a AI Compactlogix 1769-IF8 PLC card.
-Can you explain loop power & how the signal comes from the transmitter back into the input card?
-Does the Analog Out signal work in the same manner? moving a valve position
Digital signal:
DI vs DO
-Explain the wiring on how a DI & a DO signal travels back into a 1769-IQ16 input card
and a 1769-OV16 output card
thanks for helping
