I have two transmitters. One is level and the other PT. Both are reading correctly at the transmitter. milliamps are correct at transmitters. milliamps are correct at plc. Looking at it on our display in the control room it shows both transmitter milliamps at 10ma. Why? My process variables are wrong as well. displaying what ever pressure or level that corresponds to 10ma. Example. The level trans was displaying 35inches and the milliamps were at 17.4. but in the control room I get whatever corresponds to 10ma. They are both stuck at 10ma. Both transmitters are landed on the same card. Its a control logic plc. Any ideas?
Thanks
