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
