Processor unit redundancy is available for PM858, PM861, PM862, PM864,
PM865, PM866, PM867 and PM891. In this case, the controller contains two
processor units, each including memory for system and application software. One
unit is acting as primary, the other is backup (hot stand-by). The primary processor
unit controls the process. The backup stands by, ready to take over in case of a fault
in the primary. The changeover is done bumplessly and in less than 10 ms. During
the changeover, the process outputs are frozen.
Following a changeover, the system operates as a system without redundancy with
only one processor unit in operation. You can replace the malfunctioning processor
unit while the system is running. After the replacement is carried out, the system
once again has a redundant processor unit.
If an error arises in the backup unit, you can also replace the backup unit while the
system is running.
Errors which occur in the backup unit can never affect the primary unit's operation.
The primary unit and the backup unit are logically separated from one another.
Hardware errors in the primary processor unit cause the system to perform a correct
changeover. These hardware errors are single errors.
The application programming and the communication are totally unaffected by the
redundancy.
