Abstract: Disclosed is a method of controlling a load in a railway signaling system, the method comprising providing a first autonomous controller connectable to the load and a second autonomous controller which is redundant with the first controller such that there is no single point of failure; operating the first and second controllers in one of two modes. There is an on-line mode wherein both controllers provide power to the load to control the load such that current through the load is shared between the first and second controllers. There is an off-line mode wherein a single controller does not provide power to the load and the other controller continues to operate on-line to control the load, whereby control of the load is uninterrupted.

Abstract: A system and method provide vital shutdown of a remote slave unit linked by a fiber optic connection to a local, checked redundant master unit with two paired computers. Each computer sends a life signal to an associated local vital supervision card (VSC) and copper to fiber converter (C/F converter) for transmission via fiber to a corresponding fiber to copper converter (F/C converter) on the slave unit, then to a corresponding remote VSC. Each local VSC controls power to a corresponding second local VSC-associated C/F converter, and each remote VSC controls power to a corresponding second remote VSC F/C converter. A VSC detecting an incorrect life signal signature removes power to the corresponding controlled converter and, optionally, to a respective local or remote I/O rack, thereby shutting down the slave unit.
