3.6.2 Modbus
If you’re using Modbus RTU over an ethernet connection, you’ll need to designate a slave unit
identifier. Configure that identifier here.
Figure 3.20
Modbus Configuration
Option Description
Modbus TCP/UDP
Slave Unit Identifier
This designator is used for Modbus RTU over an Ethernet
connection. The default slave unit identifier is 0, which disables this
feature.
To enable this option, enter a TCP/UDP slave address from 1-254 in
this field. In most instances, the identifier is typically set at 1.
Default: 0 (disabled)
