Hey there, I've been experiencing some difficulties when trying to upload a program from a Micro 850 PLC for the first time. Since I don't have a file saved on my laptop, I used CCW to 'Discover' the PLC and then tried to upload the program via USB. However, I encountered an error message stating: "Upload failed for: Cannot import "c:\users\documents .. etc … The file is either corrupted or has an invalid format." I also attempted the same process over Ethernet, successfully pinging the PLC and establishing a connection, only to receive the same error message. I am trying to upload into my VM to see if that makes any difference.
Could it be possible that the discrepancy lies in the versions being used? It is plausible that the PLC program was developed using a more updated version of CCW that is not currently in your possession.
I hadn't actually checked on that yet, but I'll take a look today. I assumed CCW would provide a specific prompt for it.
I just recalled that there is a PV 800 HMI connected to the Micro850 PLC that I successfully uploaded using Connected Components Workbench (CCW). This suggests that the software versions must be compatible to ensure proper functionality.
To determine the micro850 firmware version, you can access it through the properties tab in RSLinx. It is crucial to ensure that the firmware version matches the version of Connected Components Workbench (CCW) that you have open. When attempting to connect to a device with an outdated firmware version, CCW may not function properly as it always opens the latest version installed. To avoid this issue, it is recommended to open a project with the correct firmware version for the device or create a new project using the older firmware version. Keep the CCW software open, close the project, and then try to upload with the correct firmware version open. If you encounter difficulties, consider checking if a memory module is installed. You could potentially transfer the program to another PLC for testing. Alternatively, using an SD card with a backup program could also be a viable solution if hardware compatibility is a concern.
Is your mode switch set to "Run" mode? If so, consider switching it to "Rem" mode. I have encountered issues with not being able to upload from a Micrologix 1400 when it was in run mode. This resulted in a similar error message to what you are experiencing. It seemed unusual to me that the error did not specifically mention the run mode as the cause of the upload issue. You may be experiencing the same issue.
I feel your frustration, it seems like you're having a tough time with this. Based on the error message, it sounds like the issue could be with the program file itself. Either it's corrupted, or its format is incompatible with the software you're using to upload it. I'd suggest trying to open the program on the PLC directly if possible, or reaching out to the program's creators for a new file, if you don't have any other backups available. Running it in a VM might work, but that depends on whether the program was designed to run in that sort of environment. As always, it could be a compatibility issue with your software and the PLC, so make sure you have the latest versions of everything. Best of luck!
Hey, it indeed sounds like a frustrating situation. You might want to ensure that the correct version of Connected Components Workbench (CCW) that matches your Micro 850 firmware version is installed. If you're still encountering issues, consider another path - exporting the whole project from the PLC and importing it onto your laptop. Remember to also check your VM settings - sometimes certain permissions or sharing options need to be toggled on for specific hardware/software interactions. Let us know if any of these worked!
It sounds like you've covered all the bases when it comes to the uploading process. One possible reason for the error could be file compatibility issues — your current CCW version might not support the PLC's firmware version. Consider updating your CCW to the latest version, after checking the firmware of your PLC. If there's no discrepancy there, then it could be a connection issue despite the successful ping. Try switching the Ethernet cable if possible. Finally, regarding the VM, do ensure it has proper drivers for the USB - that could be another hitch. Hope this helps!
It sounds like you've tried reasonably thorough troubleshooting already. One possible issue could be a compatibility problem between software versions. Make sure the version of Connected Component Workbench (CCW) you're using is compatible with the firmware running on the PLC. You might need to update either the firmware of the PLC or your CCW software. Another possibility could be a corruption of the original program in the PLC. If that's the case, you might need to reach out to whoever had the original program for a copy. Trying to upload into a VM to see if that makes any difference is worth a shot, too. Good luck!

Answer: Answer: The error message may indicate issues with the file format or corruption of the program file. Ensure the file being uploaded is in the correct format and is not corrupted.
Answer: Answer: Upload errors can occur due to various reasons such as incorrect file format, corrupted program file, communication issues between the PLC and the software, or configuration settings mismatch. Troubleshooting these aspects can help resolve the upload errors.
Answer: Answer: Uploading into a VM may not directly solve the upload errors. It is recommended to focus on resolving potential issues related to file format, file integrity, communication settings, and software configuration to successfully upload the program from the Micro 850 PLC.
