CAN-HSB High Safety Bus

For the safe operation of CAN-HSB, both CAN-interfaces of an OPEN 3100 EMS C2 or an OPEN 4100 EMS C2 will be used. With these interfaces, the field level can be operated in a ring and therefore it is possible that the field devices can be operated during an interruption or failure of the CAN network.

Hot Standby Controller (Redundancy)

For a maximum operational safety, the system can be designed as a redundant system with two OPEN 4100 EMS/R. Therefore two OPEN 4100 EMS/R controllers are operated at one CAN-bus. The first controller (Primary) normally handles all monitoring and control functions. The second controller (Secondary) is in a hot standby mode. If the Primary controller breaks down, the Secondary controller will automatically take over all monitoring and control functions, with no downtime. The option ‘Redundancy’ must be activated for both controllers.
