Looper89 Posted May 16, 2016 Report Share Posted May 16, 2016 I am having problems getting any output or input from a V200-18-E4XB attached to a V570. I believe the wiring is correct and power is being supplied to all the appropriate places. I also believe the jumpers are set properly. AO to B, AI to A. SB 177 shows that the snap in module is installed and responds when the module is removed. The AI always shows 32767. When using a volt meter to measure output voltage of the AO, I never get more than a few mV not matter what values is written the to output register. I also tested a DO without success. Is there a definitive way to determine if the snap in module is damaged? . Thanks for your time. Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted May 17, 2016 MVP 2022 Report Share Posted May 17, 2016 Verify that power is connected to both sides of the module. V2 is important. Maybe take a picture of your module wiring and post it. Joe T. Quote Link to comment Share on other sites More sharing options...
Looper89 Posted May 18, 2016 Author Report Share Posted May 18, 2016 I purchased a new V200-18-E4XB, plugged on, connected it and it works. I wish I knew what the issue was with the damaged one. Quote Link to comment Share on other sites More sharing options...
cantcliff Posted May 18, 2016 Report Share Posted May 18, 2016 Any chance it's set to current versus voltage? Quote Link to comment Share on other sites More sharing options...
MVP 2022 Ausman Posted May 19, 2016 MVP 2022 Report Share Posted May 19, 2016 Any chance it's set to current versus voltage? Or it's completely missing some jumpers? It sounds like you have done everything ok, but perhaps you didn't have one of the plugs fully inserted, which you corrected in fitting the new module? cheers, Aus Quote Link to comment Share on other sites More sharing options...
