Triconex 4352AN Tricon Communication Module (TCM)

Triconex  4352AN Tricon Communication Module (TCM)

Triconex 4352AN is a communication module used in the Triconex safety system. Below are some points to keep in mind when working with this module:

The Triconex 4352AN module is used for communication between Tricon controllers and other devices, such as distributed control systems (DCS), programmable logic controllers (PLC), and human-machine interfaces (HMI) .

The module supports a variety of communication protocols, including Modbus, OPC, and HART.

It has two serial ports and two Ethernet ports, and can be used in redundant or non-redundant configurations.The module can be replaced online without halting operations, which reduces downtime and ensures continuous production.

The Triconex system has built-in diagnostics and redundancy management, which are transparent to the user. This means that the system can detect and manage faults in individual modules, field wiring, and sensors automatically.

When programming the Triconex 4352AN module, keep the following in mind:

The module can be programmed using TriStation software suite, which provides tools for every step of the safety lifecycle, including system configuration, programming, and documentation.

TriStation Emulator can be used for offline emulation and testing of applications without the need for a physical controller.

Safety Validator is a tool that can be used to automatically test and document the application logic, which can save time and effort during validation and revalidation.

The Triconex system also provides Enhanced Diagnostic Monitor for status and health information, TriStation SOE retrieval display and analysis for resolving process issues, and Report Generator for custom reports across multiple controllers or projects.

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.
