Triconex Main Processor Baseplate Kit 2101

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.

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.

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)

Model 9764-310 RTD/TC/AI Termination Panel

The Model 9764-310 RTD/TC/AI Termination Panel with industry-standard

signal-conditioning modules may be cabled to the Model 2352 Analog Input

External Termination Panel Baseplate. The RTD/TC/AI Termination Panel

supports 16 points and each Analog Input Module can support up to two External

Termination Panel. The input-signal conditioners are manufactured by Analog Devices™.

The Model 9764-310 panel comes with a:

• 10-foot cable

• Mounting plate

The Model 9764-310 panel has a barrier strip with four compression screw

terminals for connecting an AI Module to 16 analog inputs. The panel accepts

power (+24 volts DC) from the AI Baseplate or from direct connection to the panel.

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.
