Mitsubishi PLC comms

Hi All,

I have two Mitsubishi Q series PLC's ( Q03UDECPU ).

Both are connected via a basic ethernet switch.

I need to read and write about 100 words of data between each PLC.

This is not a high speed application.

This is a new project using GX Works 2.

What is the best way to achieve this task.

Any help or examples appreciated.

Thanks in advance.

Hello,
You will need to go into the PLC parameters in GX Works 2, under the Ethernet port tab go to open settings. In there you can configure the communication between the two PLC's.

Hope this helps.

We used the UDP socket blocks. It is not easy but there is an example. One PLC will need to be the 'server' and respond to 'client' requests.
We have an example that talks to our motion controller here

This program will need to be modified to be the server.
