FX Series Protocol

5 posts in this topic

Hello, all.

 

I wrote the communication driver for connecting to the Mitsubishi FX series controllers in C # using the programming port. I searched for this on the Internet and did not find it. Found this here https://github.com/blueskit/MitsubishiPlcProtocol.git, but there is no implementation of the protocol that is used when connecting via the port for programming. This is my first experience in writing such a program. I still have a lot of things to do in my project, in particular, there is no check of the checksum of the received package, well, various checks of the connection, etc. I will be glad if you help me refine it. The program is working, I spread it for those who had the same problem as me. Checked on the controller FX1N.

@Jirrr If you need to communicate with FX PLC. I recommend to use MX Component that can use C#, VB.Net to commnicate with FX PLC and have example for coding.
