Hi guys,
I'm new to Omron PLCs and am facing some trouble with the analog input modules CJ1W-AD04U. I used the IO Table in CX-Programmer to configure my analog cards (settings: 4-20mA, 0-32000 scale, "Switch to High value" at sensor error). When I connect a current injector (@ 4mA) to a channel the reading goes to 0 from 32767 (indicating no error). But when I scaled the current injector up (say to 8mA) the reading stays the same. I should get some value right? Anybody ever faced this problem before? FYI, I have no problems with my analog output cards on the same rack.
