I got the S7 part clear. my issue was that in S5, while reading from AI using FB250, i was not receiving data as per process. Is there any structure to FB250 that helps me make sense of data I'm reading.
For Ex: for a 16 bit AI module, im reading an Analog input(4-20mA) attached to transmitter of range(0-100C)
according to scaling, IW=0 for 4mA and IW=32767 for 20mA.
for 70C of transmitter, I am receiving IW=5672 which do not make sense.
