The engineering name of Mitsubishi PLC programming software is defined by itself, as long as there are no special symbols and illegal symbols in the name, it is allowed.

The complete Mitsubishi PLC project folder contains the following files:

1.resource- is a folder to save comments and parameters); PLC corresponding to this project

2.GPPW。 GPJ-is an auxiliary file of the program. Only by opening it can the project be opened;

3.GPPW。 GPS-is the link file of the program, and the project cannot be started when it is opened;

4.4. Project. INF-It's the information file of the project. I can't understand the garbled words in it, but if it's lost, the program can't be opened.

5. Project database. MD B- is an engineering database that stores the internal data of the program.

I hope my answer can help you!
