The NKMP03 redundancy cable is used to link two multi-function processor modules in a redundant configuration.
In operation, both processors continuously exchange status and control information through the cable. One processor operates as the active unit while the other remains in standby mode. If a fault occurs in the active processor, the standby unit immediately takes over without interrupting system operation.
This ensures continuous control system availability and prevents downtime in critical industrial processes.
Within ABB Bailey INFI 90 / Net 90 systems, the NKMP03 plays a redundancy coordination role:
It is a key component in fault-tolerant DCS architectures.
The ABB NKMP03 is commonly used in:
