Triconex Tricon™ v9–v11 Tricon Controller Chassis

System Configuration

Physically, a basic Tricon controller consists of Main Processors and I/O modules,

communication modules, the chassis enclosing the modules, field wiring connections, and a

TriStation PC. This section briefly describes these components and provides general

specifications.

Tricon modules are field-replaceable units consisting of an electronic assembly housed in a

metal spine. Each module has a protective cover that ensures no components or circuits are

exposed even when a module is removed from the chassis. Offset backplane connectors make it

impossible to plug a module in upside down, and keys on each module prevent the insertion of

modules into incorrect slots. The Tricon controller supports digital and analog input and output

points, as well as pulse and thermocouple inputs and multiple communication protocols.

Tricon Controller Chassis

A Tricon controller can include a maximum of 15 chassis, housing any appropriate combination

of input, output, communication, interface, and hot-spare modules. There are three types of

chassis: Main, Expansion, and RXM.

• The Main Chassis houses the Main Processor modules and I/O modules. The Model

8110 Main Chassis houses up to six slot sets of I/O modules and the Model 8120E

Enhanced Performance Main Chassis houses up to five sets of I/O modules. The I/O

modules in a chassis are connected via I/O expansion bus ports that are triplicated RS

485 bi-directional communication ports.

• An Expansion Chassis (chassis 2 to 15) houses up to eight slot sets of I/O modules and

HART™ Interface Modules. The Expansion Chassis connects to the Main Chassis by

means of a triplicated RS-485 bi-directional communication port. Generally, the last

Expansion Chassis must be located no more than 100 feet (30 meters) from the Main

Chassis or an RXM Chassis.

• An RXM Chassis houses a Primary or Remote RXM Module set and six slot sets of I/O

modules. An RXM Chassis enables a system to extend to remote locations up to 7.5

miles (12 kilometers) from the Main Chassis, using SRXM modules.

Triconex Tricon™ v9–v11 Fault Tolerance

Fault Tolerance

Fault tolerance, the most important capability of the Tricon controller, is the ability to detect

transient and steady-state error conditions and to take appropriate corrective action online.

With fault tolerance, there is an increase in safety and an increase in the availability of the

controller and the process being controlled.

The Tricon controller provides fault tolerance through Triple Modular Redundant (TMR)

architecture. The controller consists of three identical system channels, except for the Power

Modules which are dual-redundant. Each channel independently executes the control program

(also referred to as the TriStation application) in parallel with the other two channels. Hardware

voting mechanisms qualify and verify all digital inputs and outputs from the field; analog

inputs are subject to a mid-value selection process.

Because each channel is isolated from the others, no single-point failure in any channel can pass

to another. If a hardware failure occurs in one channel, the faulty channel is overridden by the

other channels. Repairs consist of removing and replacing the failed module in the faulty

channel while the Tricon controller is online and without process interruption. The controller

then reconfigures itself to full TMR operation.

Extensive diagnostics on each channel, module, and functional circuit immediately detect and

report operational faults by means of indicators or alarms. The diagnostics also store

information about faults in system variables. If faults are detected, the operator can use the

diagnostic information to modify control actions or direct maintenance procedures.

Because the triplicated system operates as one control system, the Tricon controller can be

programmed with one control program that terminates sensors and actuators at a single wiring

terminal.

Controller Features

The Tricon controller is a state-of-the-art programmable logic and process controller that

provides a high level of system fault tolerance. To ensure the highest possible system integrity

at all times, the Tricon controller includes these features:

• Provides Triple Modular Redundant (TMR) architecture whereby each of three

identical system channels independently executes the control program, and specialized

hardware/software mechanisms “vote” all inputs and outputs.

• Withstands harsh industrial environments.

• Enables field installation and repair to be done at the module level while the controller

remains online. Replacing an I/O module does not disturb field wiring.

• Supports up to 118 I/O modules (analog and digital) and optional communication

modules that interface with Modbus masters and slaves, Foxboro® and Honeywell™

Distributed Control Systems (DCS), other Triconex controllers in Peer-to-Peer

networks, and external host applications on Ethernet networks.

• Provides integral support for remote I/O modules located as far away as 7.5 miles

(12 kilometers) from the Main Chassis, using SRXM modules.

• Executes control programs developed and debugged with TriStation™ 1131

Developer’s Workbench Software or TriStation MSW software.

• Provides intelligence in the input and output modules to reduce the workload of the

Main Processors. Each I/O module has three microprocessors. Input module

microprocessors filter and debounce the inputs and diagnose hardware faults on the

module. Output module microprocessors supply information for the voting of output

data, check loopback data from the output terminal for final validation of the output

state, and diagnose field-wiring problems.

• Provides integral online diagnostics with adaptive-repair capabilities.

• Allows normal maintenance while the Tricon controller is operating, without

disturbing the controlled process.

• Supports transition to a hot-spare I/O module for critical applications where prompt

service may not be possible.

Coated modules are X20 modules with a protective coating for the electronics component. This coating protects

X20c modules from condensation and corrosive gases.

The modules’ electronics are fully compatible with the corresponding X20 modules.

For simplification purposes, only images and module IDs of uncoated modules are used in this data

sheet.

2.1 -40°C starting temperature

The starting temperature describes the minimum permissible ambient temperature when the power is switched

off at the time the coated module is switched on. This is permitted to be as low as -40°C. During operation, the

conditions as specified in the technical data continue to apply.

Information:

It is important to absolutely ensure that there is no forced cooling by air currents in a closed control

cabinet, for example using a fan or ventilation slots.

B&R X20cBC0087 Bus controller

General information

Established in 1979. the Modbus protocol has approved the use of Ethernet with both Modbus TCP and Mod

bus/UDP. Today, Modbus TCP is an open Internet draft standard introduced by Schneider Automation to the In

ternet Engineering Task Force (IETF), the organization responsible for Internet standardization. The Modbus ser

vices and object model have been preserved since the original version and left unchanged for use with the TCP/

IP transmission medium.

Modbus/UDP differs from Modbus TCP in that it uses connectionless communication via UDP/IP. The advantages

of faster and easier communication with UDP/IP also brings with it the disadvantage of requiring error detection

and correction in the application layer.

This bus controller makes it possible to connect X2X Link I/O nodes to Modbus via Ethernet. The bus controller

can be operated on B&R controllers through the use of Automation Studio or on third-party systems with Modbus

TCP or -UDP master functionality.

• Fieldbus: Modbus/TCP, Modbus/UDP

• I/O configuration via the fieldbus

• DHCP-capable

• Bootp-capable

• Integrated double switch for efficient cabling

• Configurable I/O cycle (0.5 to 4 ms)

• Response time: <1 to 8 ms (depending on the load on the integrated switch)

• Validity check for command sequences before execution

Information:

With multifunction modules, the bus controller supports only the default function model in the event

of automatic configuration by the bus controller (see the respective module description).

Automation Studio V4.3 or later can be used to easily create configuration files (e.g. DCF files). All

other function models are also supported by transferring configuration data to the bus controller (e.g.

via the master environment with an SDO download).
