Abstract: An updatable, single fault impervious integrated control and monitoring system (ICMS) for airfield avionics comprising at least a pair of I/O Processors connected in parallel by two separate networks to each of a) a plurality of workstations, preferably including a Master Workstation, and b) one or more Equipment I/O Interface backplanes; said one or more Equipment I/O Interface backplanes comprising one or more programmable Equipment I/O Interface circuit card plugged therein and being structured to be programmed to bidirectionally translate at least one of a plurality of signal types required for control and monitoring of avionic equipment and convert said at least one of a plurality of signal types to and from a common signal type usable by the I/O Processors. Methods of making and using the updatable, single fault impervious ICMS are also described.

Abstract: An integrated control and monitoring system for airport avionics is made single-point-of-failure impervious by continuously operating pairs of parallel-connected concentrators, Remote Master Workstations and Remote Slave Workstations, and a pair of independent LANs each connecting one of the concentrators of a pair to the Remote Workstations. Each concentrator of a concentrator pair, while in secondary status, monitors the operation of the concentrator in primary status, and whenever it observes a failure of communication will assume primary status and continue to allow ICMS to function in a normal manner. Likewise, another Remote Master Workstation automatically assumes Remote Master Workstation status if it fails to see an operational active master station on the network.
