Hello,

As part of a project, I want to exchange data in Modbus TCP from my computer to another remote computer.

In fact, I set M340 PLC with unity pro so that the controller executes the commands and I can read the output back. the protocol used is Modbus TCP. the responses of the controllers come in the form of frame and I have to sent these frames modbus tcp to another remote computer that retrieves and displays.

My question is how can I send the frames I got the controller from my computer to a remote computer via Modbus TCP?

Thank you.
 
an M340 PLC is being read by computer1, and you want to send the data to another remote computer2.

computer2 must either be a modbus master reading computer1, or computer2 must be a modbus slave and computer1 must write the data to computer2.
 
Can't you read data directly from PLC via Ethernet/Modbus TCP also with another computer?

If you wan't use computer between, then you need some Modbus server software (both master and client or OPC server), there are plenty of them, but usually you need also license for it.

Hello,

We have a program, PeakHMI MODBUS Master/Slave Relay Ladder Logic, $29.00, it can be a TCP master and slave and do what you have described.
