Triconex Tnident Accessory Kit 8401
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.
