Mitsubishi plc

both are in different backplane


whats the program to communicate

I am sorry, I am unable to offer such a program. I have never done this before. I would give you one if I had. All I can do is try to explain what needs to be done. Never before did I communicate two MELSEC with each other. Either I use remote IO to get IO data to the PLC, or use a PC to get data from the PLC. What you need to do is doable, I can say this from my understanding of Melsec protocol, but is no trivial undertaking that I could do in five minutes. Sorry to disappoint.

As Alfredo stated, it is not an easy task, however, in those links I posted there are some examples, again I have never done PLC to PLC on Q series only Scada to PLC, I have always used NETH cards to do the communication this is easy, no programming only configuration of memory areas. As you only have a couple of bits to link between the PLC's if there is a bit of spare I/O why not wire them and do it digitally it sounds like you only need to send an enable signal to another PLC to run a motor.

I want use modscan with Mitsubishi plc
Data transfer between
Fx5ujplc and system
How can I see data transfer properly o r not

Spatil, I suggest you start a new thread. Also need a bit more information I assume you mean FX5 and what is the other system

Spatil: assuming you mean TCP If you open GXWorks3, top menu goto TOOLS, Predefined protocol support function you can select Modbus there, needs configuring to what you need. If it is 485 port then you can select Modbus there.
here is the manual.
