Schneider Triconex 4351A TCM Controller Communication Module

Product Description

The Triconex 4351A is a high-reliability Tricon Communication Module (TCM) designed exclusively for Tricon v10.0 and later systems. This module establishes secure, high-speed industrial network connectivity between your Tricon controller and external automation systems. It enables seamless integration with TriStation software, safety networks, Modbus masters, Modbus slaves, and distributed host computers. Each module features a robust architecture that optimizes data transmission across dual copper Ethernet infrastructure and four isolated serial channels. Engineering teams can easily deploy this module to manage critical industrial communications without risking process interruption.

Key Features and System Capabilities

• Multi-Protocol Support: Executes TCP/IP, Modbus TCP/IP Master/Slave, TSAA, TriStation, SNTP, and Jet Direct protocols.
• Network Reliability: Dual copper ports support critical Peer-to-Peer network communication and Peer-to-Peer Time Synchronization.
• Flexible Serial Bridging: Four serial ports run independent Modbus configurations to interface with Legacy field instruments.
• GPS Connectivity: Serial port 1 delivers specialized interface compatibility with Trimble GPS clock synchronization systems.
• TriStation Integration: Serial port 4 provides a dedicated hardware connection option for TriStation engineering software.
• Data Management: TriStation software assigns five-digit numeric alias addresses to variable names for fast Modbus data access.
• High Availability Expansion: A single Tricon system hosts up to four 4351A modules across two distinct logical slots.
• Continuous Operation: Supports safe online module replacement during live operations to maintain maximum plant uptime.
