Trusted™ Architecture |
Trusted™ Controller Trusted™ is highly compact, 240 fault tolerant TMR I/O with Modbus communications in a single 6U chassis. At the heart of each Trusted™ system is the controller chassis housing the TMR Processor, its companion slot for bumpless change out to a spare and 8 interface slots accept I/O modules, communications modules or interface modules to Expanders. Trusted™ Expander Up to seven I/O expanders, each housing up to 12 I/O slots may be located up to 10km distant, connected by separate 250Mbit high speed triplicated fibre optic links to the Controller. Save on Cost We have taken great care to make the Trusted™ product easy to use and easy to integrate into wider control schemes. So easy in fact, that by using Trusted™, you can now have the true fault tolerance of TMR at the same or lower overall cost than redundant PLCs. And that's not just purchase price; because Trusted™ TMR is packaged to make it easy to use, life time cost of ownership is significantly lower than alternative schemes. I/O Modules A wide range of dedicated modules for both analogue and digital, plus a unique "universal I/O" module that allows you to mix signal types on he same module gives maximum flexibility to closely match the application requirements. All modules have full stuck on stuck off testing, configurable line monitoring and indication LEDs per channel. I/O configuration is easily set in software with the loop parameters set by link configuration on the termination assembly. Power Supplies Trusted™ can be powered directly from a single or dual conditioned 24Vdc supply or from ac sources using the 19" by U Trusted™ modular power system to provide redundant power feeds in blocks of 50 watts. Supply configuration can be either 100% redundant or n+1. Integration Tools The familiar tools in Trusted™'s IEC1131 compliant toolset allow you to define up to 250 individual programs with the flexibility to mix safety related programs and continuous process programs in the same Trusted™ fault tolerant system. The Trusted™ IEC1131 Toolset has comprehensive simulation, de-bugging and cross checking tools to help you implement the application safely. Integration Hardware A comprehensive range of I/O termination panels, power distribution units, pre-wired cable harnesses and many other integration aids make building and integrating a Trusted™ system quick and easy. Connectivity Trusted™ communicates with other Trusted™ systems, PC based graphics, PLCs and host DCS using Ethernet and TCP/IP, leveraging commercially available Ethernet hardware and software tools to build fault tolerant Ethernet LANs. Trusted™ also uses OPC (Object linking and embedding for Process Control) to give drag and drop connectivity to any OPC client with network redundancy managed by the OPC server software. |
