The following redundant I/O configurations are supported:
1. Redundant configuration with one-sided central and/or distributed I/O.
For this purpose, one signal module each is inserted into the CPU 0 and CPU 1
subsystems.
2. Redundant configuration with switched I/O
One signal module each is inserted into two ET 200M distributed I/O devices with active
backplane bus.

Note
When using redundant I/O, you may need to add time to the calculated monitoring times; see
