xii Preface Planning and Installation Guide for Tricon v9–v10 Systems Planning and Installation Guide for Tricon v9–v10 Systems 1 Introduction Controller Features 2 System Configuration 3 Theory of Operation 5 International Approvals 17 2 Chapter 1 Introduction Planning and Installation Guide for Tricon v9–v10 Systems 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 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. 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. System Configuration 3 Planning and Installation Guide for Tricon v9–v10 Systems 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. 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
