MVP 2021 Flex727 Posted March 1, 2018 MVP 2021 Report Share Posted March 1, 2018 You need to provide a LOT more information before someone can attempt to help you. What PLC? Which I/O module(s)? Is the Run command given via a Digital Output from the PLC I/O or some other communication? Has this been a problem all along or is it new? If this has been happening all along, it sounds like a logic error by the original programmer. If so, it may be a simple fix. Do you have the PLC program .vlp file? If so, attach it and someone should be able to give it a look over. Quote Link to comment Share on other sites More sharing options...

MVP 2021 Joe Tauser Posted January 20, 2021 MVP 2021 Report Share Posted January 20, 2021 The EX-A2X does not require software. What is your question? Joe T. Quote Link to comment Share on other sites More sharing options...
