I have a process running with a PLC5 and a remote 1771-A4B rack, ASB module, and some digital I/O. Occasionally (once every 3-4 months) the rack seems to lock up, it stops updating the I/O image to the PLC. Recycling the power to the rack clears the problem and away we go again. Has anyone seen anything like this, and where would my best starting point be to troubleshoot this problem? It happens infrequently and usually during production, so I don't get a good opportunity to analyze what is going on. Thanks.
