  • Digital fault annunciation simplifies troubleshooting
  • Alarm contacts, separate annunciation for major or minor faults

The GE-Emerson IC600RP551 Series Six Redundant Processor Unit acts as a switch to transfer control from one Series Six Plus CPU or I/O chain to a standby Series Six Plus CPU upon failure of the first. To accomplish this, the RPU monitors the Master CPU and I/O chain for fault conditions, and when such conditions are detected, conducts an orderly transfer of control to the standby CPU. 

A bumpless transfer (without loss or interjection of data) can be accomplished within milliseconds, while maintaining program and I/O continuity. Actual transfer time varies up to two CPU sweeps, depending where in the sweep cycle the fault occurs, and the amount of data to be transferred.

The RPU is contained in a standalone Series Six type rack and includes the following rack-mounted modules:

  • Data Control Module (required)
  • Data PROM Module (required)
  • Data Storage CMOS Memory Module (required)
  • Device Switch Module (required)
  • CPU Switch Module (required)
  • I/O Switch Module (required)
  • Main Power Supply Module (required)
  • Auxiliary Power Supply Module (optional, recommended)
  • Additional CPU and I/O Switch Modules for Auxiliary I/O (optional)

The RPU modules must be connected to two Series Six CPUs and a Series Six I/O system to complete the system configuration.
