Hi friends, from Aug 4th onwards iam getting spikes for analog inputs in our DCS for a period of 800ms. I throughly checked every thing, finally i found that the DI, DO's from MCC panels shields are terminated in the Signal Earth where Analog Input signals shields are terminated. Is there any problem with this type of termination?. i checked the induction voltage from MCC and getting around 25VAC, please suggest me in this concern. Our plant is 8months old only. DCS is Siemens Make Simatic PCS7, and the transmitters are Yokogawa make.
