■ Hot Standby CPU Redundancy (including new CPU module CRE020). Hot Standby CPU Redundancy is a system in which two PLC CPU units are cooperating to control the same process. There is an Active Unit that is actively controlling the process and a Backup Unit that is synchronized with the Active Unit and able to take over the process should it become necessary. The two units are synchronized when both are in Run Mode and the Backup Unit has received the latest status and synchronization information from the Active Unit and both are running their logic solution in parallel. The Backup unit is a Hot Standby unit, capable of taking over the process. Redundant I/O capability is based on the Genius I/O System.
