Eaton 9372-FB may therefore be selected

The 9372-FB may therefore be selected for critical process

applications where failure of the Fieldbus Barrier would

otherwise result in unacceptable downtime or lost production.

It is also ideal for use in Fieldbus Safety Instrumented Function

(SIF) networks in which nuisance trips cannot be tolerated.

Failure annunciation to the host control system is provided by

means of an integrated Foundation™ fieldbus device with Digital

Input Function Block capability.

In common with conventional Fieldbus Barriers, each

intrinsically safe spur is capable of supporting a FISCO or ‘Entity’

certified fieldbus device located in a Zone 0 or 1

hazardous area. The short-circuit protected spurs are

galvanically isolated from the trunk and require no protective

ground connection in the field.

The 9372-FB redundant fieldbus barrier is based on our

revolutionary 9370-FB range of products, which are supplied

as complete, factory-assembled enclosure systems that do not

require additional wiring, customised housings or complex

ancillary components. Electrical and mechanical aspects of the

design are integrated, providing the industry’s first complete,

ergonomic solution for ‘High Energy Trunk’ applications in

hazardous areas.

wiring implemented using suitably protected cable and increased

safety (Ex e) connection facilities.

Each enclosure system uses duplicated Fieldbus Barrier

modules in a redundant configuration to achieve significantly

higher system availability than equivalent ‘simplex’ units.

2787 Series WAGO Power Supplies Pro 2

Introduction

The 2787 Series WAGO Power Supplies Pro 2 are compact switched-mode

Power Supplies with a wide range of uses. The Power Supplies can be fitted on a DIN

rail.

The Power Supplies can be configured directly via buttons on the product or via the inte

grated communication interface. For this purpose, the connection is established either via

the WAGO USB Communication Cable or via an attached communication module. It is

also possible to record and evaluate various output parameters via the WAGO Interface

Configuration software, which is available separately.

The pluggable connection technology uses WAGO pluggable connectors. These allow

pre-wiring for quicker installation, as well as quicker and easier product replacement.

LEDs indicate various diagnostic messages (see section Indicators).

Triconex Communication Module InterfaceTCMI Architecture Overview

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.

TCMI connects directly to an Ethernet port of the Tricon Communication Module

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.

WAGO WAGO Power Supply Pro 2 Features

Features

• Power supply with TopBoost, PowerBoost and configurable overload behavior

• Configurable digital signal input and output, optical status indication, function keys

• Communication interface for configuration and monitoring

• Suitable for both parallel and series operation

• Snap on communication modules (sold separately)

• Free WAGO configuration software (download only)

• 2-year warranty

Smaller, but better

The WAGO Power Supply Pro 2 is smaller than its predecessor, but offers greater efficiency.

What that means to you is three times the cost savings and further crucial advantages:

First of all: The higher efficiency of up to 96 % reduces energy loss, and thus energy costs.

Second: The WAGO Power Supply Pro 2 generates less heat in the control cabinet, allowing 

corresponding savings on cooling solutions.

Third: Less warming means a longer service life of the components.

From planning, to installation, to long-term operation, the WAGO Power Supply Pro 2 saves

you even more time and money, since it can be created, planned, modified and ultimately

operated as a digital twin. All the necessary data is available in the most important 2D/3D

formats, and the communication provides transparency.

Marking compliant with EN 81346-2 is important for quick and safe installation. 

The WAGO Power Supply Pro 2 accommodates this through unambiguous imprinted connection

designations and the option of device identification through marking strips.
