The Triconex 4351A is a specialized Communication Module (TCM) designed for the Tricon safety system. It is compatible only with Tricon v10.0 and later systems. This module allows the Tricon controller to communicate with TriStation, other Tricon or Trident controllers, and external hosts.
It supports communication over Ethernet networks. The module is essential for integrating your safety system with the wider plant network. It enables data exchange with Modbus master and slave devices. This connectivity ensures that your critical process data is always accessible.
The Triconex 4351A is built with robust hardware. It contains four serial ports and two network ports. It also includes a debug port for Triconex use. The unit is designed to handle high data loads efficiently. It is a key component for modern industrial automation.
🛡️ Technical Architecture
The module provides extensive connectivity options. Each serial port is uniquely addressed. You can configure each port as a Modbus master or slave. Serial port #1 supports either the Modbus or the Trimble GPS interface. Serial port #4 supports either the Modbus or the TriStation interface.
The Triconex 4351A supports an aggregate data rate of 460.8 kilobits per second. This rate applies to all four serial ports combined. This ensures fast and reliable data transfer.
For network connectivity, the module features two copper Ethernet ports (NET 1 and NET 2). These are 10/100BaseT Ethernet ports with RJ-45 connectors. They support various protocols including TCP/IP and Modbus TCP/IP. NET 1 also supports Peer-to-Peer and Peer-to-Peer Time Synchronization protocols.
