1.During commissioning, we ll do loop checks.it means from
field instrument( PT,TT,FT,LT or switches) the signal is
checked with the DCS.
for example : consider a PT,we ll simulate 4 to 20 mA in the
instrument and the same value should be shown in the DCS also.

open loop and closed loop
closed loop for controllers to control the process.for
