TomB Posted October 19, 2019 Report Share Posted October 19, 2019 Hi, new to Unitronics, familiar with AB/Rockwell. I'm sitting on a job site and am looking for any help I can find. We had a panel that had a hi voltage hit, and we believed it fried one of the IO-AI4-AO2 cards, as all the input values on the LED's are showing out of range. I replaced this, and same issue, no resolution. I've checked every input wire to the card - all are ~ 4 mA. Value to the HMI/PLC is maxed out. Not sure where to go from here. My engineer back in factory says just replace the whole damned set up - but that seems like an extreme move, as all the other cards seem to be working fine. Any chance that card before (same type) or after (AI8) or the flex cables could be contributing to the issue? I'm lost ... Quote Link to comment Share on other sites More sharing options...
