What is IO routing and how is it used?
Definition
Using IO routing, process data is exchanged between two PROFINET IO systems.
Example
A process controller user program controls a robot.
IO routing makes input/output data of the robot controller accessible to an IO controller for
the control level that can both read and write the data.
IO routing is a function of the IO-Base user programming interface that is configured.
