Hello,
I am trying to get a Yokogawa Hart pressure Transmitter and a Rosemount Temp Transmitter to read on a 1769-IF4 module on an L33ERM CompactLogix. The displays on the transmitters do not energize, and the values on the card show the cards code for "Undervalue".
I programmed the transmitters/sensors to scale 4-20ma within the desired process values.
I put a 250 ohm resistor in series on each side of polarity on different test. No difference in value.
I know these cards aren't meant to support Hart communication, but has anyone found a unique way to get these to connect?
Thanks
