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.

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.

Product Description

The Triconex CM3201S2 Communication Module is a highly reliable and efficient

component of the Triconex safety and control systems, specifically designed 

for industrial automation and critical processes.

It ensures seamless communication between the Triconex controllers and various field devices,

enabling high-speed data transfer and improved system integration.

This module adheres to rigorous safety and performance standards,

making it an ideal choice for industries requiring maximum uptime and precise control.

The Triconex CM3201S2 communication module is a workhorse for exchanging critical data within safety instrumented systems (SIS).

Function: Enables seamless communication between SIS components and external devices.

Applications: Ideal for process industries demanding high reliability and performance.

Key Features:

High-Density Digital I/O: Handles 32 digital channels for efficient data exchange.

Supports Industry Standards: Communicates via protocols like Ethernet, ControlNet, and DeviceNet.

Robust Design: Built for harsh industrial environments, operating from -40°C to 70°C.

Technical Specifications:

Form Factor: Compact design for easy integration into existing systems.

Power Supply: 24 VDC for compatibility with typical industrial control systems.

Networking Speeds: Supports Ethernet (100 Mbps), ControlNet (10 Mbps), and DeviceNet (5 Mbps).

Models 3502E, 3503E, and 3505E can perform a self-test to detect a “stuck-open” condition

in which the circuitry is unable to determine whether a point has entered a shutdown state.

The ability to detect the point of shutdown is an important feature

since most security systems have a power failure trip feature.

In order to detect the presence of a “stuck-open” input,

the switch within the input circuit needs to be turned off in order for the opto-isolated circuit to read a zero input (“off”).

The I/O communications processor will freeze the last reading while the test is running.

All TMR digital input modules support the hot standby feature and require a separate

external termination panel (ETP) with cable connections to the Tricon backplane.

Each module is mechanically keyed to prevent improper installation in the configured chassis.

supplies provides logic power to the I/O chassis and

another set of dual power supplies provides power to

the field instruments. This redundant power

architecture provides protection against a single power failure.

Using TriStation™ 1131 Workbench software, you

can configure each Triple Modular Redundant (TMR)

UIO point as one of the following:

 Supervised Digital Input, 24 VDC, with 1 ms

Sequence of Events (SOE) capability

 Supervised Digital Output, 24 VDC

 Analog Input, 0-20 mA, configurable: with or

without HART pass-through

 Early-stage I/O wiring and late-stage project changes

The SIE has ETPs for termination of field device

signals. Each ETP point comes pre-configured with a

pass-through pluggable conditioning module (PCM).

A range of other PCMs is available.

The EcoStruxure Triconex Safety Intelligent Enclosure (SIE) provides

an integrated solution designed to be mounted close to field instrumentation to reduce cabling

The SIE includes Tricon™ CX Universal Input/Output (UIO) modules, power supplies,

and External Termination Panels (ETPs) that are pre-installed and tested,

and can be connected to a wide range of field devices.

The factory-manufactured SIE supports Schneider Electric’s Flexible Lean Execution strategy,

which shortens project schedules and reduces the risk of startup delays.
