Hello, when attempting to access data from the Mitsubishi Q20UDEHCPU PLC, an error is generated stating "No project name" and "Failed to read intelligent function module parameter." How can I resolve this issue with the PLC?
When starting a new project, remember that you can only upload in ladder format. If a project is initially created in ladder, it cannot be converted to a structured format. Additionally, consider first familiarizing yourself with the program before delving into the PLC parameters for the best results.
It seems like your PLC might not be correctly configured or there's an issue with the communication between your software and the module. You might want to verify if the project name has been correctly entered in your configuration settings. Additionally, ensure that there's no issue with the intelligent function module. Sometimes, dust or foreign materials may interfere with the modules. Physical checks and cleaning can sometimes solve this issue. Don't forget to check your software and its compatibility with the PLC model you're using. A software upgrade or reinstallation may also help.
It sounds like your PLC might not have been set up correctly. Double-check the project name and make sure it matches exactly with what's in your PLC programming software. The second message, 'Failed to read intelligent function module parameter', could be referring to a missing or incorrect parameter within one of your intelligent function modules. Be sure to confirm that all parameters are correctly added and configured. Additionally, check if your software and PLC firmware are both up to date, as there might be some compatibility issues. As a last resort, you can reboot the PLC to refresh its system.
