adjusting offset and gain of analog i/o

3 posts in this topic

Hi everybody, i am new to omron plc. i have cj1m cpu11, cj1w-ad081, and cj1w-da041. i have manage to read the analog input data, i also could output data to analog output. both of the analog i/o are configure in current (4-20 mA) mode. my question is how to adjust the offset and gain of the analog i/o. i have read the manual (w345) and could not understand it. my input reads like this: input current: read value 4 mA +4 20 mA +3994 my output : output value: read value 0000 3,96 mA 4000 19,85 mA please help me, if possible please give it in example. thank you.

I have never had to do this, but from looking at the manual, is a step by step procedure that needs to be followed. I suggest setting the PLC up on the bench, print out the relevant pages, and go from there. The only thing that I can see that may be slightly foreign, is the setting of the offset/gain bits, but if you managed to get the Inputs/Outputs working, then you should be able to work them out also.
