Hi all!
I am currently trying to setup multiple Modbus slave devices and I cannot discover the devices.
I am using a MGATE MB3170 as a Gateway and 4 meter as Slave Devices.
Reading the meter manual said devices are setup with 48 as default slave Id.
I have a RS485 going from the gateway to the first meter then to the 2nd and so on. A to A, B to B and Comm to Comm. Ending with 120 ohm resistor.
My question is: If I connect all those 4 devices they will share the same slave Id which is 48. Do I need to change the slave id in each meter in order to pull data out ? Or the devices are smart enough to change automatically ?
Do I need to turn off and on after RS485 cable installation ? Do I lose the meter data if I restart the meter ?
Thank you in advance.
