Hello, I have encountered a recurring problem where downloading a PLC revision causes us to lose rung comments. The PLC model in question is L82ES running on revision 33. Is there a solution to this issue that can be implemented?
If you're looking to download the program documentation, it can be found within the controller properties. Make sure to check there first. Additionally, it's important to ensure that the L82 has sufficient memory capacity. If the program is nearing its limit, it may deselect the option automatically.
Avoid toggling this feature on, located in the routine tab. It's easy to accidentally activate it.
When searching for the option to download documentation within a program, it can usually be found in the Controller Properties under the Project Tab. If you're unable to locate it, ensure to check if the L82 has sufficient memory. If the program is near its maximum capacity, the download option may be automatically deselected.
I am grateful for your input and will be testing out your suggestions. I will provide an update once I have completed the download process. Thank you for your assistance and valuable time!
That's definitely a frustrating problem to deal with! It sounds like the issue may be related to the PLC software you're using. Not all versions retrieve comments by default. I suggest checking the PLC software settings to ensure comments are included when downloading a revision. If that doesn't work, consider upgrading to a newer software version or contacting the support team for your software, as this might be a known issue they can assist you with.
Hey there, losing rung comments can indeed be frustrating. Have you tried storing them in the PLC instead of the programming software? This way, anytime you download a revision, the comments remain associated with the logic rather than the revision. Also, always remember to back up your project files before implementing any changes—this way you have a safety net if anything goes awry.
