Hi
Thanks for you kind answers ¡
I have tried with Modbus Poll but there is not communication¡ Timeout error.
At the beggining of my application I test with a Tag Status generator UINT16 and Slave ID "1" but without communication. The manufacturer of device said that ID by default is 1¡ That ID is in a Holding Register, 40009.
The master of application is the unistream, as I said before, but I think is not necesary to config an ID for it? or YES? Do I need to config the master with a ID?
I want to stablish a basic communication reading a Only Holding register, 40001, and after the others.
I show some pics of my config as attach
I have appreciated all comments, thanks again.
