Overview

The Triconex 4351A is a Tricon Communication Module (TCM) used in industrial automation for secure Ethernet and Modbus connectivity. It features four serial ports and two 10/100BaseT copper Ethernet ports, supporting protocols like Modbus TCP/IP, SNTP, and TSAA. It facilitates seamless Distributed Control System (DCS) integration and is designed to be hot-swappable.

Tricon Communication Module (TCM)

The Tricon Communication Module (TCM) enables a Tricon controller to communicate with Modbus devices (masters or slaves), a TriStation 1131 PC, a network printer, other Triconex controllers, and other external devices on Ethernet networks.

Each TCM has four serial ports, two Ethernet network ports, and one debug port (for Invensys use).

Sample of the TCM Communication Capabilities

A single Tricon controller supports up to four TCMs, which reside in two logical slots. This arrangement provides a total of sixteen serial ports and eight Ethernet network ports.
