How to configure AI card to match field reading with DCS reading?
We have recently installed ABB DCS 800 XA system in our plant. Since installation we are facing the problem of field instrument reading connected as AI to DCS AI815 card doesn't match with the reading displayed in DCS. We have calibrate our filed instrument, it is ok. We have checked the scaling in DCS. It is alos OK.
For example : ENdress & Hauser FLowmeter connected as 4-20mA inout to DCS.
At zero flow it the flowmeter it shows 41 m3/Hr flow in DCS. Please help to resolve the problem.
Earlier we were using same flow meter with siemens DCS PCS7 it was showing correct value.
