Modbus Unit Identifier

This value is used to select Modbus unit identifier / slave address. When using Modbus TCP the
value 255 must be used, and this field is ignored as the IP address is used to access the correct
device. When using Modbus UDP the values and their significance is explained in table below. Values
from 1 to 247 and 255 can be set.
Table 21. Modbus Unit Identifier field description when using Modbus UDP
# Unit identifier
0 Broadcast
1...247 Slave address
255 Non-significant
The value 0 can be used to control several devices with a broadcast message, e.g. to command all
devices to stop at the same time. This feature will also work if all devices have the unit identifier
value 255.
