5.2.1 Setting Modbus Address

To determine the address on the Modbus network, the device has two rotary switches, S1
and S2, located on the top panel of the device.
It is possible to set the device address from 0 to 99.
The formula for setting the address is as follows:
Address = S2 • 10 + S1,
where S1 and S2 are values of switches.
For example:
Switches set as in figure above will set the device address to 11.
