TRICONEX 2755
Product Name
TRICONEX 2755 TMR (Triple Modular Redundant) Communication Interface Module
—— A critical communication gateway for TRICONEX Tricon Safety Instrumented Systems (SIS), designed to enable secure, redundant data exchange between Tricon safety controllers and third-party industrial systems (e.g., DCS, SCADA, HMI). It is widely used in high-risk industries such as oil & gas, petrochemicals, and nuclear power, ensuring uninterrupted communication for safety-critical operations.
2. Product Description
The TRICONEX 2755 addresses three key challenges in safety system communication: single-point communication failure risks, protocol incompatibility between diverse industrial systems, and data transmission latency affecting real-time monitoring. Leveraging TRICONEX’s proprietary TMR architecture and multi-protocol support, it delivers three core values:
2.1 TMR Redundant Communication Architecture
The module integrates three independent communication channels, each with a dedicated CPU, protocol processing unit, and physical interface. It adopts a “2-out-of-3” voting logic for data validation: when transmitting or receiving data, at least two channels must generate consistent results to confirm data integrity. If one channel fails (e.g., Ethernet port damage, protocol stack error), the remaining two channels automatically take over without communicatio
