RTU540 TCP/IP SLAVE ID Change
Hi
The scada program I'm using doesn't support 255 slave id. It needs to be between 1 and 31. I don't know how to change it

Hi,
AFAIK, it is not possible to change the unit ID of the RTU540 to any other value other than 255. Manufacturers of Gateways/Bridge devices usually set 0 or 255 as the unit ID for such devices, when the device itself is acting as a Modbus TCP/IP server. Values 1-247 are reserved for Modbus RTU slave devices connected to a gateway unit's RS485 port, if any.
