can the latest communication module be installed on a V7.2 install?
Have an out of town install that is having occassional PLC connection issues, and want to eliminate any driver issues, and there is no money in this existing job to pay for an upgrade from V7.2 to V7.5
No, sorry, that doesn’t work.
What kind of issues are you having? If it’s just a lot timeout errors in the logs, which may or may not cause stale tags depending on various timeout/stale threshold settings, there’s nothing an upgrade would fix.
