Redundancy

Using Cluster functionality with 2 ControlUnits.

Two ControlUnits on two different computers

Two ControlUnits on two different computers are synchronized to each other using an external database. Externally, this cluster of ControlUnits appear as one computer, so that all WorkUnits continue to work with one "visible" ControlUnit. The WorkUnits are not able to detect the loss of one of the ControlUnits inside the Cluster, preventing an interruption of the workflow in the event of a hardware failure.
