Product Details:

Description:

The Tricon Communication Module (TCM), which is compatible with only Tricon v10.0 and later systems, allows the Tricon to communicate with TriStation, other Tricon or Trident controllers, Modbus master and slave devices, and external hosts over Ethernet networks. Each TCM contains four serial ports, two network ports, and one debug port (for Triconex use). Each serial port is uniquely addressed and can be configured 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. Each TCM supports an aggregate data rate of 460.8 kilobits per second, for all four serial ports. Programs for the Tricon use variable names as identifiers but Modbus devices use numeric addresses called aliases. Therefore, an alias must be assigned to each Tricon variable name that will be read by or written to a Modbus device. An alias is a five-digit number which represents the Modbus message type and the address of the variable in the Tricon. An alias number is assigned in TriStation.
