hi,
i'm a student doing my final project in data acquisition from trivector meter (ER300P - L&T make), at a substation near my college. In this i use the modbus rtu mode. here i have to connect 28 devices in a daisy chain connection. i can communicate with one device if i allocate a device address '01' but if i connect one more device to it, i get responses from both the devices randomly when polled continuously. i tried the modbus scanner too but it couldn't even get the connection.
is there a way i can find the 'device address'??
