We are working in lignite based power plant.
The supplier has provided the Main Control System DCS, ABB along with FSC, Honeywell. Most of the measurement, control, monitoring, recording & trending is done by the DCS.
Tripping philosophy incorporates the software issues OFF command to MCC from DCS.Besides, "Release" hardware command through relay is issued with the help of FSC.
Thus i would like to understand:
1.Need of FSC
2.There is no field monitoring for DIs.
3.Why AI have additional termination module for FSC.
3 Why TCs are not directly connected to FSC & taken as 2-wire transmitter.
Thanks in advance.... I will come with more query
