Triconex 通信接口模块 (TCMI) 4351A B
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)
The TCMI connects directly to an Ethernet port of the Tricon Communication Module (TCM) in the Tricon
Safety Manager. The TCM implements the TSAA communication protocol on Ethernet networks for
communication with the Tricon controller. TSAA Protocol is a messaging protocol used in application programs
that read and write data to the Triconex controllers and is utilized by the TCMI.
The TCMI requires the use of a pair (two; one-part number 4351A and one part number 4351B) of TCMs in
the Triconex system. The TCMs connecting to the TCMI must reside in a single Triconex System logical slot
and shall occupy the left and right module physical slots (which comprise a single logical slot). At least 1 port
