I checked the I/O => UOP => and verified the HOLD was ON. My communication to the PLC is hard wired signal.

I am having similar issue with my R2000iB Robot. While it is running the main program, at certain steps it will stop and give the following error Alarm Detail: "SYST-034 HOLD signal from SOP/UOP is lost" Initially I thought there might be a problem in the program. I restored the backup softwear, but this did not eliminate the problem. If there was any alteration to the program causing the issue that would have been eliminated by restoration, or am I missing anything? I have also been directed to check all the input output signals to PLC, I asked my controls techs to look into that. they came back to me and said they did not notice anything obvious. I am lost now, anyone have had similar issue and what the remedy was?
