The module can be configured to route Modbus data in one of three modes:
Reactive Tag mode
Schedule Tag mode
Unscheduled mode

The Reactive Tag routing mode allows mapping of virtual Modbus registers to Logix tags
across multiple controllers. In this mode the Modbus Router will redirect a Modbus message
to a Logix controller at a preconfigured path.
Thus the routing of Modbus read and write register requests is managed by the Modbus
Router and converted to direct Logix tag read and write functions.
Figure 3.17 - Reactive Tag mode configuration
The Reactive Tag mode is configured in two steps. First the user must create a Target Name
(CIP path to the destination Logix controller) which will be used to link the Modbus function
and register selection to the destination Logix tag.
