SilverHawk Safety Controller
Available from Argenia Systems Inc.
Our SIL 3 compliant controller designed for Railway Signal and Communications, Track Switch Point Protection, Remote Object Control and Grade Crossing Systems and general Interlocking applications use this controller.. It has a rich list of interfaces to support most of the common media. The development package allows non programmers to develop application code using our Function Block programming platform. Using Eagle CAD, draw a block diagram of the system you want using our library of block elements designed for typical railway usage. Special blocks support axle counters, track databases, lookup tables, speed enforcement, penalty braking and more. Then connect the inputs and outputs of the blocks and compile and download to the controller. No programming language or knowledge is required. This produces a safe and certified application program operating in the SafeNet O/S protected sandbox.
A vital Supervisor co-processor performs health checks on the main processor and will shutdown the system on any fault.
