However, two commissioned devices randomly fail to count the inputs. I've duplicated the error on the test bench. Could I have 2 faulty devices? Or could it be an AM or AT function block error? The actual program is considerably more elaborate...I've loaded just the basics in an attempt to troubleshoot the problem...without success. Ideas? Thanks for looking.

Show at the attached video to see the difference between simulation and online monitoring. Attachment Test.wmv (14 Downloads)
