Chint DTSU666 through Growatt Shinemaster

[rantwolf]

Hi.
I have a setup with a Growatt Shinemaster.
It's a Modbus collector for up to 64 devices.

My problem is, when I want to setup my DTSU666, the connection can't be established.
I realized that the Growatt Shinemaster converts the Modbus RTU signal into 'Modbus-TCP' and not 'Modbus-RTU over TCP'.

Is it possible to change the initial setup and add a selection between 'Modbus-TCP' and 'Modbus-RTU over TCP'?
Or does anyone have a config file to place it directly?

Maybe i'm understand your problem, but i can't test it, what is the solution.
The integration use default modbus TCP, not modbus-RTU over tcp:
