Dear All,
I want to use a 4-20mA output from Omron AO module, so I did the following configuration: PLC used CJ1M-CPU22, rack 00 CJ1W-AD041, rack 01 CJ1W-DA041. I set channel 1 as 0-10V output and channel 2 as 4-20mA output. In my program, I have already set bits 2010.00, 2010.01, 2010.02, 2010.03, A502.00 and A502.01.
I retrieve a value from the analog input module, and do some conversion and output it to analog output channel 1 and 2.
when I measure voltage at channel 1, it works well. But when I measure current at channel 2, it doesn't work, measurement shows in the multimeter is 0.
I also monitor the value in my program, channel 1 and channel 2 get the same value.
Can anybody tell me why?
Thanks.
