So after hours searching google and looking through everything I could find here, I have an issue that has stumped me for quite some time and was wondering if you might be able to help. I frequently make online edits to our SLC 5/05 that runs our process. We are constantly evolving the process to make improvements, and we are a 24 hour operation, so that means stopping to download is not entirely happy times. Lately in the middle of making changes I have been getting the pop up error that says 'Program could not be compiled! Online Edit Error Going Offline'. Then if I don't shut the process down and do a download, sometime later(usually about 8 or 9 hours) the program loaded on the 5/05 becomes corrupt and the process stops in a bad way. I have tried the techconnect bulletin for RSLinx that changes the CIP connection parameters, and that seems to only have made it worse, so I set it back to default. I am thinking that I will try changing the CPU next. I cannot upload the program, as it is considered proprietary by my company, but if you look at my screenshot you can see the rung I was editing when it happened most recently. The compare for greater than T104:39.ACC was what I was changing, and I changed the value from 490 to 499. I got the first 9 typed when this happened this particular time. It seems to be random and it doesn't seem to matter what part of the program I am working on either. Also, it appears that we have plenty of CPU memory left. Any help or suggestions would be greatly appreciated.
Thank You
