Tricon Communication Module

The Tricon Communication Module (TCM) is compatible with Tricon v10.0 and later systems only.

Allows Tricon to communicate via Ethernet with TriStation, other Tricon or Trident controllers, Modbus master and slave devices, and external hosts.

Each TCM contains 4 serial ports, 2 network ports, and 1 debug port (for Triconex).

Each serial port is uniquely addressed and can be configured as a Modbus master or slave.

Serial port #1 supports Modbus or Trimble GPS interface. Serial port #4 supports Modbus or TriStation interface.

Each TCM supports an aggregated data rate of 460.8 Kb/s for all four serial ports.

Tricon programs use variable names as identifiers, while Modbus devices use numeric addresses called aliases.

Therefore, each Tricon variable name must be assigned an alias that will be read by or written to the Modbus device.

An alias is a five-digit number that represents the Modbus message type and the address of the variable in the Ticon. An alias number is assigned in the TriStation.

Any standard Modbus device can communicate with Tricon via TCM, provided an alias is assigned to the Tricon variable.

The alias number must also be used when the host accesses the Tricon through other communication modules.

Each TCM contains two network ports - NET 1 and NET 2. Models 4351A and 4353 have two copper Ethernet (802.3) ports and Models 4352A and 4354 have two fiber optic Ethernet ports.

NET 1 and NET 2 support TCP/IP, Modbus TCP/IP Slave/Master, TSAA, TriStation,

The NET 1 also supports the Peer-to-Peer and Peer-to-Peer Time Synchronization protocols.

A single Tricon system supports up to four TCMs, which must reside in two logical slots.

Different TCM models cannot be mixed in a logical slot.

Each Tricon system supports a total of 32 Modbus masters or slaves, including network and serial ports.

The hot standby feature does not apply to TCMs, but you can replace a defective TCM while the controller is online.
