Product Overview
The TRICONEX 4352B is a Tricon Communication Module (TCM) providing fiber-optic Ethernet connectivity for Tricon safety systems, enabling SIL 3-rated data exchange with DCS, SCADA, and peer Tricon controllers. Featuring dual redundant 100 Mbps fiber ports (MT-RJ) plus four configurable RS-232/RS-485 serial ports, it supports TriStation, Modbus TCP/RTU Master-Slave, Peer-to-Peer UDP/IP, SNTP time sync, and TSAA protocols for seamless integration. Oil & gas, refining, and power engineers deploy it in ESD, Fire & Gas, and burner management networks where fiber eliminates EMI concerns over long distances. TMR architecture ensures communication fault tolerance, with comprehensive diagnostics (PASS/FAULT/ACTIVE/FIRM/LINK/TX/RX LEDs) and hot-swappable replacement maintaining 99.999% availability. Maximum 31 peer nodes and 32 Modbus endpoints per system support large-scale safety architectures. (148 words)
Key Functions
Dual Fiber Redundancy
Two independent 100 Mbps fiber Ethernet ports provide primary/backup paths; automatic failover maintains SIS-DCS communication during cable faults.
Multi-Protocol Support
NET1/2 handle Modbus TCP Master-Slave, TriStation, Peer-to-Peer UDP/IP, SNTP; serial ports support Modbus RTU plus 9 Modbus functions (01-08,15,16).
Galvanic Isolation Protection
500 VDC port isolation prevents ground loops; fiber eliminates electrical noise coupling in high-voltage motor control environments.
Real-Time Diagnostics
Per-port LINK/TX/RX LEDs plus module PASS/FAULT/ACTIVE/FIRM status enable immediate network troubleshooting during safety audits.
Application Scenarios
SIS-DCS Integration
Refineries connect Tricon ESD to DeltaV/Yokogawa DCS; Modbus TCP exchanges safety status while fiber spans control room distances reliably.
Multi-Node F&G Networks
Offshore platforms link 24 Triconex controllers; Peer-to-Peer UDP/IP shares detector data while TSAA synchronizes system time across fiber ring.
Burner Management Historians
Power plants stream NFPA 86 events to OSIsoft PI; SNTP maintains time accuracy while serial Modbus RTU interfaces legacy RTUs.
HIPPS Remote Monitoring
Gas plants communicate with distant HIPPS cabinets; 100 Mbps fiber supports high-volume proof test data without EMI interference.
