4.4 IO routing
4.4.7
Example of the main and robot controller writing output data
Description
Both the IO controller for the process level and the IO controller for the control level will write
input and output bits in output submodule 100. A transfer relation is therefore configured for
address 1 in the transfer submodule.
The table and figure show which bits are written by the IO controller for the control level and
which by the IO controller for the process level.

Note
The process controller user program always writes byte-oriented on the IO Base user
programming interface.
Bits 100.0 and 100.1 are, however, replaced by the bits of the IO controller for the control
level by the IO router before outputting to the submodule.
