PC application is connected to master Gateway embedded controller over USB. Gateway is connected to number of slave embedded controllers over Modbus RTU.
I need to assign Modbus addresses to slave devices. Somehow I need to inform PC application as to what slave devices are on the modbus. Then, PC application would assign 8-bit modbus addresses (through gateway) to slave devices.
Any ideas how modbus addresses can be assigned, configured, or programmed in slave devices.
I didn't find it in the modbus spec. Could you provide internet links?
