Product introduction：
Processor unit redundancy is available for PM861, PM864, PM865, PM866, 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.

S800 I/O units are connected to the two CPUs via the optical ModuleBus and two TB840 cluster modems on each S800 I/O cluster . The built-in electrical ModuleBus on the TP830 baseplate cannot be used for connecting S800 I/O in a redundant system.
