The old 3.xx version of RSLogix 5 had a nice "feature" that when ever you entered a value to a data table address during editing, it won't write that value to the data table when you except the rung! I took a look at the revision notes and there is an entry for r3.21.00 that read "preventing data table edits made during an online edit from being sent to the PLC when the rung is accepted." I don't remember what I did to work around that problem but it sure sounds like what you guys have been chasing. Whenever we added a timer or counter we would have to go back to the data table and reenter the information a second time.
