AC500-eco Modbus TCP/IP slave
I am working on the project where I need to set an 10 AC500-eco PLCs as a server. Could you please provide any documents related on how to configure it.
Also, sample examples would be a big help. What functions block do we need in the program? I guess the function block "ETH_MOD_Mast" will be only for the client configuration. I have to write 10 words and read 10 words to and from the AC500 PLC. How is the modbus addressing done in PLC?
Need advise.
Thanks

Greetings,
Whie you are using Modbus TCP protocol, you have to define your variables under Global Variables with %MWxxx syntax.
Also i've added a project example, you can see communication with 2 PLCs through Modbus TCP protocol.
Hope it hepls you.
