I have one PC on which we installed kepware software (MODBUS-TCP client). Now we connect one Gateway device (MODBUS-TCP server). We have connected 10 devices to this Gateway device through a wired connection. Now as per my understanding, if I want to configure client, then one way is just allocate 10 different register address for each device parameter like 10000 for device-1 (voltage), 10001 for device-2 (voltage) and so on. But if all devices are in the same category (Means they are providing their voltage), then I think this is the wrong way for development. So can we do like allocating each device as one unique number (we can called it a device identifier), and get their parameter value of the device through register address 10000? If its possible, then can you explain to me how to achieve this or do you have any reference document?
