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

have been created to provide TRICON™ diagnostic information.
