The Triconex 4351A Communication Module enables Tricon systems (v10.0 and later) to communicate reliably with external devices and networks. Moreover, it supports TriStation, other controllers, Modbus devices, and external hosts over Ethernet. This module ensures seamless connectivity for industrial automation and safety-critical applications.
Key Features
- Ports:
- 4 serial ports (RS-232/RS-485, DB-9 connectors)
- 2 network ports (copper or fiber-optic depending on model)
- 1 debug port for Triconex diagnostics
- Serial Port Configuration:
- Ports can operate as Modbus master or slave.
- Port #1 supports Modbus or Trimble GPS.
- Port #4 supports Modbus or TriStation.
- Modbus Compatibility:
- Requires alias numbers for variable mapping.
- Supports standard Modbus functions.
- Network Protocols:
- TCP/IP, Modbus TCP/IP, TSAA, SNTP, and more.
- NET 1 supports Peer-to-Peer and Time Synchronization.
- Hot Swap Capability: Faulty modules can be replaced online, however, the hot-spare feature is unavailable.
- System Limits:
- Maximum 4 TCMs per system in two logical slots.
- Maximum 32 Modbus masters/slaves across all ports.
