When ControlNet Router is configured as a ControlNet Target and Modbus TCP Master, a
controller (e.g. Logix Controller) can own the ControlNet Router via Scheduled ControlNet
(e.g. via 1756-CNB/R) while the ControlNet Router exchanges data with multiple Modbus TCP
Slaves.
The data from the controller (e.g., Logix Controller) can be exchanged with the ControlNet
Router using the Scheduled ControlNet input and output assembly. This data, in turn, can be
mapped to any of the Modbus TCP Slaves being written to or read from by the ControlNet
Router.
