CatUnitronics Posted December 9, 2020 Report Share Posted December 9, 2020 Currently have a USP-156-B10 that loses communications to a server application as to where it was working last week. Prior to this a screen would pop up and indicate that the screen needs reset when nothing has changed or touched. The unit was replaced a few months ago and now this. The unit that was replaced had a bad screen and tried to reload the software and this did not work. Can a digital I/O module cause communication issues with the HMI? Thanks Quote Link to comment Share on other sites More sharing options...
