Triconex DCS Systems Oct 28, 2021

Triconex DCS Systems offers unprecedented support for communications integration via industry-standard protocols. To date, the TCM incorporates an Embedded OPC Server and Modbus TCP/IP together with Safe Peer to Peer and other standard Triconex features. In addition, the TCM supports full TCP/IP and routing functions for use with LANs and WANs.

To help ensure uncompromised safety, the TCM acts as a layer that isolates the Tricon safety system from control network and private LAN nuisances. The TCM itself is designed to degrade safely and recover gracefully. Support for redundant connections helps ensure that there will be no “loss of view” of the safety system from the DCS. Like other Tricon family products, the TCM is TUV approved for use in systems up to SIL 3.

A powerful, scalable design with assurance of continuous operation, the Tricon system complies with international safety standards such as IEC61508 and fulfils the requirements for applications such as Emergency Shutdown (ESD), Fire and Gas Protection (F&G), Burner Management (BMS), High Integrity Pressure Protection (HIPPS) and Turbomachinery Control (TMC). The redundant high availability architecture provides a flexible, robust, reliable and powerful solution that is ideal for clients looking to achieve environmental and safety excellence.
The Tricon system is a must for clients who need to maximize the safety and performance of their assets. If you are challenged with reducing investment and lifecycle costs, meeting new safety standards, combating tough competitive pressure in your markets as well as the welfare of your employees and the environment, then the Tricon system is designed for you.

THE TECHNOLOGY THAT MAKES IT WORK

The ultra-high reliability and availability of a Triconex ESD system is based on Triple Modular Redundancy (TMR) featuring:
• Triplicated 2-out-of-3 voting principle for high integrity, error-free and uninterrupted process operation with no single point of failure.
• Three isolated main processor boards performing extensive internal diagnostics. Each processor can be replaced online with automatic reprogramming upon insertion in a running system.
• Input and output modules that consist of three isolated independent legs, each module can be removed from service for maintenance or repair without interrupting or stopping the process or disturbing field wiring.
• System diagnostics that indicate a failure of any single active component without causing a shutdown action.
Thereby, allowing maintenance personnel to take necessary action while the process is still running.
The system can be customer configured for different modes of operation. For example, in a 3-2-1-0 mode of operation, where one of the triplicated channels fails, it transfers to a dual fail-safe operation. A failure of a second triplicated channel results in a transfer to single fail-safe operation.
CERTIFIED AND TESTED
Triconex rigorously tests its system hardware and software to meet or exceed the highest national and international standards for reliability and availability:
• ANSI/ISA, IEC, API, and HSE
• Factory Mutual (FM) and Underwriters Laboratories (UL) listings
• Electromagnetic compatibility (CE Mark)
• Certified by TÜV Rheinland* to SIL 3 applications and by CSA/NTRL/C
*Many safety system suppliers are certified by TÜV. Be sure to ask which modules are certified and request a copy of restrictions and requirements (safety guidelines) issued by TÜV. Triconex is pleased to provide you with a list of all our certified modules.
