Hello all,
First off just want to say thanks for all the tips I've received from this site. Very helpful in times of the good ol' google search for a PLC rookie. I've been reading these forums for a few years now and decided to register as I'm not having much luck with the current venture we are on.
We currently have a machine with a l55 processor v16.3. 3 times in the past 6 months while the line is running fine we were told that the PLC faulted out and cleared the program. Unfortunately this happened during off shift and our technician did not connect to PLC to look for faults prior to reloading program??? after 1st time we installed new battery. Each time the battery fault was on and a new battery was installed. Fault was never recorded. Sorry...
has anyone heard of similar issues with an L55??
Long story short boss man wants a l72 processor installed.
Any recommended versions to go along with the l72?? I've heard version 29 isn't very reliable??
Any programming issues to look out for??
A few years back we had similar issue with an L55 and replaced it with an l62 and had the line down for 2 days as our PID loops were no longer working properly. After several attempts troubleshooting with rockwell one particular engineer let us know it was a problem with our scan time.
Compatibility chart on rockwell's website indicates there are no known issues or dependencies
Just trying to get my ducks in a row prior to the upgrade.
If you need some more information please ask.
Thank you for the help
