While using RSLogix v34, a contractor made some minor offline changes (specifically alias tags) to a project and attempted to download it to the PLC. However, the download failed and removed the project from the PLC. Subsequent attempts with the latest revision also failed, with error messages stating "Error: Couldn't be found" and "Error: Failed to download add-on instruction(s)". The contractor encountered the same error during the initial download attempt. Despite all previous revisions working correctly before, they all result in the same error now. Troubleshooting steps such as cycling/reseating the card and connecting directly to the card have been tried without success. Are there any suggestions or solutions for resolving this issue?
Before the contractor downloaded the project, what was its version? To find out the version of your old project, you can save it as an l5k file and open it in Notepad. Additionally, you may also be able to check the version on the CPU in Linx by clicking on the processor.
After terminating the contractor, the next step would be to conduct a thorough verification process to ensure the program is error-free. Following this, the safety features should be unlocked before attempting to download the program once more.
To optimize the program and resolve any issues, I recommend exporting it to a L5K file and then re-importing it. This process typically helps to clear up any lingering issues. Thanks, Mark.
It seems like there may be a hardware failure, especially if it involves Guardlogix. In this case, it would be wise to contact Rockwell for assistance. Simply terminating the contractor may not solve the issue, as they still need to be paid and could have valuable information regarding the cause of the failure. It is important to ensure they fulfill their contractual obligations.
If I understand correctly, you believe it's a hardware problem that could lead to another costly PLC being damaged if I keep him around. I guess I'll have to be a Terminator and say "I'll Be Back!"
This sounds like an issue I encountered a while ago. Have you checked if there is enough memory on the PLC for your project? Sometimes, projects with sizeable add-on instructions can inflate the overall file size, causing the download to fail due to insufficient memory. Furthermore, make sure all add-on instructions are compatible with the version of RSLogix you're using. In some cases, you might need to import your add-on instructions again. Lastly, ensure your communication path to the PLC is correct and stable. Best of luck!
You might want to try deleting the AOP (Add-On Profile) and then reinstalling it. The error messages you're getting suggest that the software doesn't recognize the add-on instructions necessary for the PLC to function. If deleting and reinstalling doesn't work, I would recommend reaching out to Rockwell Automation directly. It's odd that all previous revisions that used to work are now throwing errors—there could be a deeper issue at play here. You could also try uploading the project from another PLC of the same model to check if the problem is with the PLC itself or the project file.
It sounds like a frustrating situation! Have you tried checking the project for any missing or corrupted add-on instructions? Sometimes the alias tags can cause issues if they're not defined properly in the current version of the project. Additionally, ensure that the firmware on the PLC is compatible with your RSLogix version. It might also be worth reviewing the communication settings to make sure they’re still configured correctly. If all else fails, consider backing up what you can and performing a factory reset on the PLC, as a last resort; just be aware that you'll lose any existing project data. Good luck!
It sounds like a frustrating situation! One possibility could be a mismatch between the version of RSLogix and the firmware on the PLC—sometimes, updates in software can create compatibility issues, especially with add-on instructions. Have you checked to ensure that everything is on the same firmware version that supports the features you’re trying to use? Additionally, if there are any unused add-on instructions in the project, you might try removing them temporarily to see if that helps with the download. Lastly, consider looking at the project’s configuration settings to ensure that everything aligns with your PLC setup. Good luck!
