  1. Hello, Back in December 2017, we replaced a customer's PLC-5 control system with a CompactLogix.  Everything was working fine until about a month ago, when they started having an I/O fault, Code 16 - I/O module connection failed on required module.  At first it was showing up on multiple modules, and also the end cap.  However, after a few more faults, it was only showing up on module 2.  We replaced that module and the faults stopped for about a week and then returned.  The module we replaced is a 1769-IA16. Any idea what may be causing this?  The customer insists nothing was done to the panel since the initial installation.
