Hello venugopal; The 6ES7 331-7KF02-0AB0 module is capable of measuring current in boith 2-wire and 4-wire configurations, but the selector module (on the outside of the physical module) must be set to "D" for 2-wire measurements, and to "C" for 4-wire connections. Of course the hardware configuration of the analog module channelmust be done correctly in the HWConfig editor. This is shown in the S7-300 Module Data manual: Measuring range Measuring range module setting 2-wire transducer 4 mA to 20 mA D 4-wire transducer± 3.2 mA C ± 10 mA 0 mA to 20 mA 4 mA to 20 mA ± 20 mA
