The Triconex product family includes a comprehensive range of modules. This section includes: a summary of the system components and their uses, a table that lists standard products and their model numbers, and a summary of specifications for each standard product in the Tricon family

Tricon Communication Modules (TCM) support a number of Triconex protocols and applications and user-written applications on Ethernet (802.3) networks, including TriStation, Modbus TCP and OPC. It also supports RS-232 and RS-485 serial communication with Modbus devices, TriStation 1131, and GPS for time synchronization. • Enhanced Intelligent Communication Modules (EICM) support RS-232, RS-422 and RS- 485 serial communication with Modbus devices and TriStation 1131. • Network Communication Modules (NCM) support a number of Triconex protocols and applications and user-written applications on Ethernet (802.3) networks, including TriStation 1131. • Safety Manager Modules (SMM) act as an interface between a Tricon controller and a Honeywell Universal Control Network (UCN), one of three principal networks of the TDC-3000 DCS. • Hiway Interface Modules (HIM) act as an interface between a Tricon controller and a Honeywell TDC-3000 Hiway Gateway and Local Control Network (LCN).

The Tricon controller has been certified as complying with multiple internationally recognized standards by the following internationally recognized certification agencies, these certifications have qualified the Tricon for use around the world in safety critical applications. Test reports from the various certification agencies are available upon request.

HARDWARE

The Triconex system usually consists of the following typical modules:

Main Processor modules (triple).
Communication module(s) .
Input and output modules: can be analog and/or digital and work singular or in hot-spare (standby).
Power supply modules (redundant).
Backplane(s) (chassis) that can hold the previous modules.
System cabinet(s): can compact one or more chassis in one cabinet.
Marshalling cabinets to adapt and standardize interface connections between the field instruments and the Triconex system cabinets.
Human machine interface (HMI) to monitor the events.
Engineering workstation (EWS) for programming. monitoring, troubleshooting and updating.

SOFTWARE

The Triconex main processors can communicate with the so-called TriStation 1131 application software to download, update and/or monitor programs. These programs are either written in:

Function Block Diagram language,
Ladder diagram language, or
Structured text (Pascal like) Language.
Cause and Effect Matrix Programmable Language (CEMPLE).
Besides, a Sequence of Events (SOE) recorder software and Diagnostic monitor software are implemented.
