Fault and Alarm Indicators

Fault indicators identify potentially serious problems with a module. Alarm

conditions identify abnormal field conditions such as loss of power and loss of communication.

If a fault or alarm indicator is on, you should consult the appropriate section of this

chapter and take appropriate action. This action may include replacing a faulty

module or repairing a faulty circuit or device.

Identifying Fault and Alarm Conditions

You can identify alarm and fault conditions in the following ways:

• By examining the indicators on the front panel of each module and consulting this chapter.

• By using the Diagnostic Panel in the TriStation application. 

For more information, see the TriStation 1131 Developer’s Guide.

Triconex Communication Interface Module (TCMI)

The TCMI is a standard Honeywell product that provides interface between the Fault Tolerant Ethernet (FTE)

based Enhanced Universal Control Network (EUCN) and Triconex TRICON Safety Manager System.

The TCMI is a redundant device capable of:

• Bi-directional communication with Triconex systems 10.3 and above.

• Execution of data mapping of TRICON memory tables to EUCN format

• Data conversion to EUCN data types (Tag. Parameter), engineering unit and EUCN communication functions.

• Execution of read and write function to TRICON memory tables

• Definition of signal alarm conditioning and messaging on the EUCN for alarm handling, annunciation

and diagnostic status reporting

• Direct peer-to-peer communication with other EUCN connected devices as Enhanced HighPerformance Process Managers (EHPM), Enhanced Logic Managers (ELMM) or Honeywell Safety

Manager (SM)

• Communication with operators, engineers, and maintenance personnel at the Universal Stations, EST & ESVT via ENIM.

• Support of higher level strategies through communication with Application Modules and host

computers on the Local Control Network via ENIM.

• Database restoration of TCMI Module from the History Module via ENIM.

• Available in two hardware mounting form, front and rear cabinet access mounting (MC-ZTCMIR or

MC-TCMIR1), Front only cabinet access mounting (MC-ZTCMI2 or MC-TCMIR2)

Communication Modules

• 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).

• Advanced Communication Modules (ACM) allow a Tricon controller to interface with 

a Foxboro Industria Automation (I/A) Series DCS and TriStation 1131.

Functional Overview

The TCMI performs the same functions as the Honeywell Safety Manager Module (SMM) in the Tricon, but

across the EUCN.

The TCMI converts Triconex data to EUCN data types (Tag. Parameter), performing engineering unit

conversion, alarm handling, annunciation, diagnostic status reporting, and EUCN communication functions.

The standard TCMI scan cycle is 0.5 second.

Operator and application access to TCMI is executed by use of the Local Control Network (LCN) and the

Enhance Network Interface Module (ENIM).

The TCMI Module database is configured from the TPN Native Window environment using the TPN Data

Entity Builder. Once loaded into the TCMI node, this TCMI configuration data can be saved on the History

Module, and downloaded over the EUCN to the TCMI. The ladder logic program for the Triconex TRICON™

is developed using the Triconex TRISTATION workstation. Once loaded in the memory of the TRICON™

Enhanced main processors, the control programs are saved in the TRISTATION database, which can save

multiple ladder logic programs under separate file names. In addition to integration of Triconex system data

points into standard TPN/TPS operating/engineering environment, some additional maintenance displays

have been created to provide TRICON™ diagnostic information.
