Description

A PC station contains an IO controller user program known as the IO controller for the

process level that controls its IO devices via a CP 1626.
Outside the PC station, there is an external IO controller known as the IO controller for the

control level that can write and read input/output bits of the IO controller for the process level

via the IO router.
Process data is exchanged using the IO router functions.
