What is PLC raw value ?
PLC raw value is the internal counts used by CPU of a programmable logic controller (PLC)
PLC Input module convert field value (Analog - ma) to internal value .
0-20 mA range = internal value of 0 to 32000
4-20 ma range = internal value of 6400 to 32000
Analog input value from (4-20 ma) from field device is converted to 1-5 v by PLC i/o modules.
