Dear Sir,
Device id is set in gate builder, on "device". If you use a gateway you must associate the gateway IP address with DeviceId in Protocol configuration.

Hi,
Winlog send frames in modbus TCP and modbus RTU over TCP. Your gateway converts them into Modbus RTU.
The device id that sends Winlog is what you insert in Gate Builder.
Putting the Device ID instead of IP address is a nonsense!

Dear Sir,
its should transfer from modbus TCP to RTU right ?
Yes
but how can i choose the RTU device when the option onyl to target ip address ?
When you insert "Device" number in gate configuration, this is the Modbus device address. Please read the help of Modbus RTU and Modbus TCP, all these questions have already been answered.

Best Regards
