Hello, I am attempting to establish a connection between a PLC (Matsuhita Nais FP1 C40) and FPWIN Pro software using a USB 8550 programming cable. I have successfully installed the driver for the cable (CH340 COM3). However, when I launch FPWIN Pro 7 and attempt to create a project from the PLC, I encounter an issue. The PLC initially shows as being in programming mode, but after a few moments, an error message appears. The error message, translated from German, reads: "An error occurred in online mode: Comment memory does not exist." Additionally, when using FPWIN GR to download from the PLC to my computer, I receive the error message "42 From PLC: Basic procedure error - Non-supported error." It then indicates that the upload from the PLC was completed successfully. Can anyone provide guidance on how to troubleshoot these issues? Thank you.
While I am not familiar with this particular PLC, it appears to have some similarities to Mitsubishi's system. When attempting to upload, you may encounter difficulties if you are trying to access comments that are not present within the PLC. In Mitsubishi systems, there are tick boxes in the dialog box for reading/writing or verifying with the PLC. In the attached image, you can see that the comments and symbols are not selected. I cannot speak to how your software handles this issue, but I recommend focusing on reading the program and parameters only.
I appreciate your assistance, however, there are no customizable options in FPWIN Pro for checking. I am only able to initiate the download process. The settings that can be adjusted are limited to the interface settings such as baud rate and bits.

One way to upload program information is by navigating from the Menu Bar to "Project" -> "New" -> "PLC" in order to transfer the entire project from the PLC to Control FPWIN Pro7. Another option is to upload program code and PLC configuration by selecting "Online" -> "Upload program code and PLC configuration" from the Menu Bar. If a project does not already exist, only the Mnemonic code will be displayed. The program code can be corrected in cases where the original program cannot be used for specific reasons. However, once uploaded from the PLC, all documentation details of the program, such as variable names, will be lost. If you are experiencing this issue, it may be the problem you are facing.
Upon attempting to download a program from the PLC as per your instructions, I encountered an issue where I could not view the program. An error message displayed on the image reads: "The program at block address '582' in the FPWIN GR network could not be created."
It sounds like you're facing a couple of tricky issues there. Let's try to break it down. The first error you mentioned, "An error occurred in online mode: Comment memory does not exist" may suggest that there's a mismatch between the comments included in your project and those in the PLC memory. It could help to double-check that all comment references are correctly addressed in your program. As for the second error "42 From PLC: Basic procedure error - Non-supported error," it's likely related to incompatible program instructions or parameters. You might want to make sure that the function or procedure you're trying to execute is supported by your PLC model (Matsuhita Nais FP1 C40). Also, ensure the proper specification of parameters for the instructions being used. If these approaches don't solve the problem, you might consider reaching out to the product support to get a more specific guidance. Hope this helps!
It sounds like you're dealing with a tricky situation. These types of issues can sometimes be caused by a mismatch between the PLC's firmware version and the version of FPWIN Pro software you're using. It might be useful to check if your PLC's firmware is up-to-date, or if there's an updated version of the FPWIN Pro software that's compatible with your PLC. Also, about the "Comment memory does not exist" error, it could possibly be because the FPWIN is trying to access an area of memory that isn't available. If these don't work, you might want to consider reaching out to the Matsushita Support team for more specific guidance.
Hello! I've dealt with this kind of issue before. It could possibly be due to a compatibility issue between your PLC and FPWIN Pro 7 or a fault during the installation process which could cause erroneous error messages to appear. First, I would suggest that you double check the software version against the PLC model. There could be an essential update you've missed or perhaps the version you're using isn't compatible with your older PLC model. If everything is compatible, try reinstalling FPWIN Pro 7. If there's a glitch in the software, a fresh installation might resolve it. Don’t forget to take a backup before proceeding. Another point to consider is 'Comment Memory'; ensure that they’ve been enabled in the FPWIN Pro 7 settings. Good luck!
It sounds like you're dealing with a couple of frustrating issues there! First, double-check that your PLC's firmware is compatible with FPWIN Pro 7, as mismatched versions can lead to these kinds of errors. Also, ensure that your project settings (like memory types or configurations) align with what the PLC supports. Sometimes, clearing the comment memory in the PLC can also help resolve "does not exist" errors, so it might be worth a try. If the problem persists, consider reaching out to Matsushita's support or checking forums specific to FPWIN for others who might have faced similar issues. Good luck!
It sounds like you’re navigating some frustrating issues with the connection to your PLC! The “Comment memory does not exist” error might be related to the project settings or memory allocation in the PLC itself. Make sure that the PLC has enough memory available for the project you’re trying to create. Also, double-check that your FPWIN settings match the PLC’s configuration. For the upload error, it could be worth trying a different USB port or cable if you have one handy, or even reinstalling the software to rule out any installation issues. Hopefully, one of these steps helps clear up the errors!

Answer: Answer: This error may indicate a problem with the comment memory on the PLC. Try checking the settings related to comment memory in the FPWIN Pro software and ensure that they are configured correctly. Additionally, verify that the programming cable and PLC are properly connected and that the drivers are installed correctly.
Answer: Answer: This error could be related to an unsupported procedure or function in the communication process between the PLC and the software. Make sure that the communication settings in FPWIN GR match the requirements of the Matsuhita Nais FP1 C40 PLC. You may also want to check the data transfer protocols and settings to ensure compatibility.
Answer: Answer: To establish a successful connection, first, confirm that the USB 8550 programming cable is properly connected and that the drivers are correctly installed (e.g., CH340 COM3). Check that the PLC is in programming
