I prefer other brands over Mitsubishi PLCs, but have encountered an issue with a programming software error. I am looking for a solution to download a program with multiple scans and waits without exceeding drive capacity. I have successfully added programs to other Mitsubishi PLCs before, so I am unsure why this error is occurring. Any help or suggestions would be appreciated.
Ensure that you are writing to the processor memory and not a memory card. It is possible that there is old code stored in the memory, so clearing it and resetting to the factory settings may be beneficial. Afterwards, download the program(s) and parameters again to prevent any issues.
When troubleshooting writing issues to the processor, ensure you are targeting the processor memory, not a memory card. It is recommended to clear the memory to remove any old code and reset to factory settings before downloading programs and parameters again. After performing these steps, a user reported no issues. However, there was a significant decrease in free space volume after downloading, indicating a memory shortage. The question now is how to easily increase memory capacity.
During the download process, only the parameters and program should be written. Avoid loading comments into the program memory; instead, save them on a memory card. If unsure how to increase memory capacity, consider exploring options such as upgrading to a different programmable logic controller (PLC).
When you download, only save parameters and the program to avoid loading comments into program memory. Comments can be stored on a memory card. If you are unsure how to add memory, consider switching to a different PLC. Can a Q04UDEH be substituted with a Q06HCPU?
When downloading data, are you exclusively inputting parameters and the program, without loading comments into program memory? Comments can be stored on a memory card instead. If you're unsure about adding memory, the only option may be switching to a different PLC. There seems to be aQ06UDEH processor available as a direct replacement, offering an additional 20K of memory capacity.
Hey there, it seems like you're dealing with a pretty tricky situation. Based on your problem, my first guess would be that the program you're trying to download might be larger than the capacity of the PLC's memory. As you've been able to upload other programs to the same PLC successfully, this could be the issue here. Alternatively, the PLC’s processor could be overworked, especially if it has to manage multiple tasks at once. It's all about managing the drive capacity and keeping the scan times to a minimum. I'd recommend trying to dissect the program, isolating smaller parts and uploading them individually. If that doesn't work, you might look into upgrading your PLC or revising your program. Hope this helps!
It sounds like a tricky situation you're in. Based on my experience with Mitsubishi PLCs, your problem may not be due to the hardware, but possibly a compatibility issue with the software. Try updating your diagnostic software or use an older version, it can sometimes fix issues like these. Also, ensure you have enough space on the PLC, removing any unnecessary programs if required. Mitsubishi PLCs usually handle multiple scans and waits efficiently, so double-check your coding too. Lastly, it may help to reach out directly to Mitsubishi's technical support. They're pretty responsive and could provide specific fixes given your model and problem details.
It seems like you might be running into a memory allocation issue. Have you checked the available memory before downloading the program? Also, remember that Mitsubishi PLCs typically use a cyclic scan method which may not deal well with multiple scans and waits unless properly programmed. Would recommend breaking the program down into smaller parts if possible, and observe if the error still persists. In addition, make sure your PLC is updated to the latest firmware version - this can sometimes fix unexpected software errors.

Answer: The error could be due to the drive capacity being exceeded or a specific issue with the programming software configuration.
Answer: To avoid exceeding the drive capacity, you can optimize the program code, remove unnecessary instructions, or consider utilizing external memory options if available.
Answer: When adding programs with multiple scans and waits, ensure that the PLC memory capacity is sufficient, optimize the program structure, and verify the compatibility of the programming software with the PLC model.
Answer: The error may be specific to the programming requirements of this particular PLC model, differences in memory capacity, or variations in the program structure compared to previous projects. Double-checking the settings and configurations for this PLC model is recommended.
