Triconex Communication Module Interface

Product Introduction

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 High

Performance Process Managers (EHPM), Enhanced Logic Managers (ELMM) or Honeywell Safety

Manager (SM)

• Communication with operators, engineers, and maintenance personnel at the Universal Stations, ES

T & 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

on each of the TCMs is required to configure a redundant TCMI pair. If empty ports are not available in existing

installed TCMs, then new TCMs must be installed.

Note: Up to four logical slots can be configured for TCMs. Matched pairs of TCMs can be installed in the left

and right positions of each logical slot.

For detailed specifications and technical data on the Triconex TRICON™ version 10.3 and version 11.x system

and TCM interface hardware, please refer to Triconex documentation.

Architecture Overview

The TCMI is part of the TPS/TPN product lines as shown in Figure 1.  TCMI is connected to the EUCN and

provides interface with the supplied by Schneider Electric Tricon Safety System. TCMI doesn’t required CF9

switch for FTE network connection and can be directly connect with level 2 switch, firewall features is in-built

into TCMI.

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
