I have a 331-7KF02-0AB0 analog input card (8 x 12bit) set up on a test bench communicating to a PLC over profibus witha ET 200M module (IM153-1). I have one channel set up fora 4-20mA signal. From the manual I expect 0 plc units for a 4mA signal up to 27648 for a 20mA signal. However I get a reading of 64 when I apply a 4 mA signalto the card and 27712 when I apply a 20mA. As I go through the range in between I get a lot of readings that are 64 units greater than the theoretical. See attached for reference. Has anyone come across a similar issue.
