TRICONEX 3501TN2 - Main Processor Module

TRICONEX 3501TN2 Main Processor Module is one of the core components in TRICON system, and its main functions and characteristics are as follows:

System Architecture and Redundancy Design

TRICON system adopts Triple Modular Redundancy, TMR) architecture to ensure uninterrupted control function in case of hardware component failure or transient failure. Each main processor module runs independently and does not share clocks, power supplies or circuits, thus achieving high reliability and fault tolerance.

Module function and configuration

Each main processor module is responsible for controlling one of the three independent channels of the system, and each channel contains an input/output module and a communication module.

The main processor module transmits and compares data with the other two main processor modules through the dedicated TriBus high-speed bus system to ensure the consistency and accuracy of data.

Each main processor module runs the control program written by the user, communicates with the I/O subsystem regularly, performs logical operations and generates output values.

Diagnosis and maintenance

The main processor module has self-diagnosis function, which can detect hardware faults and conduct self-test. If a fault is detected, the module will be automatically voted out of the group and the system will continue to run.

When the faulty module is replaced, the new module will re-diagnose itself, reload the control program after confirming its health, and rejoin the system after completing the "re-education" process.

The system supports the hot plug function, allowing the module to be replaced without stopping.

Communication ability

The main processor module communicates with other modules through TriBus bus, and supports communication with other TRICON or TRAC controllers, Modbus devices and external hosts.

The module supports many protocols, including TriStation, Modbus TCP and OPC.

Hardware specification

The module adopts 32-bit Motorola MPC860 microprocessor, clocked at 50 MHz, equipped with 16 MB DRAM, 32 KB SRAM and 64 MB flash memory.

The module supports cyclic redundancy check (CRC) to protect data integrity, and realizes data synchronization and voting mechanism through TriBus bus.

Application scenario

TRICON system is widely used in key safety fields, such as nuclear energy, oil and gas industries, and is favored because of its high reliability and fault tolerance.

TRICONEX 3501TN2 main processor module is the core component of TRICON system. Its independent operation, redundant design and powerful diagnostic ability make it a very reliable control solution in the field of industrial automation.
