MVP 2021 Joe Tauser Posted April 25, 2018 MVP 2021 Report Share Posted April 25, 2018 Look at the data sheet for the -E3XB and make sure you have +24V and 0V present in the right places. It sounds like you've lost one or the other. Joe T. Quote Link to comment Share on other sites More sharing options...

MVP 2021 Flex727 Posted April 25, 2018 MVP 2021 Report Share Posted April 25, 2018 Sometimes the Snap-In modules can come loose or the contacts can wear in high vibration environments. Try removing the module carefully and replacing it firmly, making sure it's well-seated. Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted April 25, 2018 Report Share Posted April 25, 2018 If you tested your I/O using INFO (Assuming you forced outputs and check input status) mode and worked properly as you stated, then it must be a programming issue.
