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.

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.

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.
