simple..
there is no hot loop check or cold loop check..
as u mentioned u have a temp transmitter and control valve
so,u have 2-AI and 1-AO
-connect the simulator by removing the DCS cable of the temp
transmitter,then give 4 - 20 mA and check with DCS reading
-give 0 to 100% command from the DCS for AO to operate the
control valve.then check the feedback in the DCS(AI)
conclusion,ur loop is ok...
