In RSLogix 500, verify comes first. I just tested this with a couple of online edits. Before accepting the rung edits verify rung is black and selectable. After accepting the rung edits it is gray and no longer selectable.

That much I know I am doing correctly

I'm not on my work computer at the moment, so I don't have the screenshot I took, but it appears that it's only a little over 50% capacity. Thank you for your response!

Stopping and downloading isn't necessarily the issue I have, it's more so that I can't make the needed programming changes and test them out and correct any mistakes without stopping the process, which is a big deal, since I'm definitely not an expert and frequently have to change my ladder logic multiple times to get the desired result.

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
