Requirements
● Fault-tolerant system as 1oo2 system
● Redundant PNIO subsystems
● Connection of two switched IO devices with CiR capability that operate simple I/O
The following boundary conditions apply:
● A CPU operates no PNIO subsystems, one PNIO subsystem or multiple PNIO
subsystems over integrated interfaces to which no IO devices, one IO device or multiple
IO devices are connected
