The figure below provides an example of the typical network setup in reactive mode, where
the Modbus Router acts as a Modbus slave device.
Figure 1.2. - Example of a typical network setup in reactive mode
By converting and redirecting serial Modbus messages from legacy devices to EtherNet/IP,
the module provides an interface for data exchange to Allen-Bradley ControlLogix and
CompactLogix platforms. This enables user to replace legacy devices and systems with
minimal effort and downtime.
The Modbus Router allows a Logix platform to seamlessly integrate into a Modbus network
with Reactive Tag Mode. The module will route Modbus message directly to Logix tags with
no need for additional ladder code.
