Hello everyone, I have a question and would appreciate it if you could help me. What happens if I go online on a compactlogix CPU 20 using an outdated acd file with the ACD running on the CPU (eg with over tags, missing lines, different lines, other new lines, ladder differences. Update your file online with the offline file or just update the offline file? Thank you very much.

your offline .acd will receive all modifications stored in online prog... but the the offline prog could be the same eg.. name and configurations...
when you go online one mensage will appears (correlating changes...) after this your prog will be updated
