Answer Posted / rahul
For loop checking we are having ILD (instrument loop
drawings)as a documents. for AI we give 4-20ma and chek in
the system if accordingly raw count is coming or not.
for AO we force from the system and check in the plant if
according to raw count current is coming or not.
for ESD loop checking raw count in the system(Triconex) is
819 - 4095 i.e for 4-20ma
if there is problem is loops then we go for backward
checking i.e from system to know where is the problem.
then we do point to point checking.
after completion of loop test we go for functional test.

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
