FLOW TRANSMITTER (FF TYPE-ROSEMONT) 

field simulation (Configuration and Simulation by the help of """"""""Trex(Communicator)""
Using procedure:- There have 4 way to connect
1.FF
2.mA
3.Hart +Power
4.Hart
we will connect prob to the FF SIDE WITHOUT USING EXTERNAL POWER BECAUSE TGE TRANSMITTER ALREADY CONNECTED TO THE DCS And after that we will see the ILD(Instrument Loop Diagram)and ISS(Instrument specification sheet) and confirm to the DCS guy all value are same.
All procedure is mention in the video watch.
if any doubt plz tell me in the comments box.
