First, as always I appreciate all the feedback.
Second, you are not going to believe what solved this programming issue. There are dip switches on the I/O circuit board that, naturally, have to be in certain positions. These were NOT overlooked. The switches were looked at several times but no one physically touched them because they appeared to be in the correct position. During the troubleshooting process connectors were removed and plugged back in. It must have been during one of these occasions that a switch was bumped ever so slightly out of position. It took a call from a tech in Germany to suggest that switches be physically moved back and forth to insure they were FULLY into position and that solved the problem.
