Delivering continuous operation

The TÜV-certified Tricon CX SIL3 system delivers the highest levels of safe operation and maximum plant availability throughout the operating life of the plant. Tricon CX combines the best of the world’s most proven Tricon and Trident platforms and can be used in both low- and high-demand modes. Inherent high integrity and high availability is built into the systems. Diagnostics and redundancy management are transparent to the user. The system adapts and maintains SIL3 even under

fault conditions. The TMR design ensures no single point of failure. The 2oo3D (two out of three diagnostic) architecture and voting eliminates spurious trips, increases plant uptime, extends plant maintenance cycles, and lowers operational costs.

Unlike other safety systems, voting and diagnostics are built in — no user logic is required. There is no need for redundant I/O modules to achieve fault tolerance. The use of a hot spare is not required to increase mean time to failure. Each Tricon CX system contains three physically separate main processor modules that continue to operate even under fault conditions. The system supports adaptive voting 3-2-1-0 or 3-2-0. Processor modules can be replaced online without stopping operation. Each Tricon CX system can accommodate up to four communications modules in two redundant pairs. Each module is physically separate, so can be replaced online if required without halting operations. Each I/O module is triplicated by design. Redundant I/O modules are not required to achieve fault tolerance. I/O modules are fault tolerant and continue to operate even under fault conditions. Modules can be replaced online, switch over is automatic, and redundancy management is transparent.

Features of the Tricon CX design include:

• High integrity and high availability are built-in

• Diagnostic and redundancy management is transparent to the user

• Maintains SIL3 even under fault conditions

• Redundant I/O modules are not required to achieve fault tolerance

• Processor, communications, and I/O modules can be replaced online without halting operations

• Modifications can be made without stopping operations
