TRICONEX 4210 controller

TRICONEX 4210 controller

The TRICONEX 4210 is a control system product, specifically a controller for the Invensys Triconex system.

The following are its main functions:

Support for digital and analog input and output points: This means that the TRICONEX 4210 can receive and process both digital signals (such as switching status) and analog signals (such as continuously changing values of temperature, pressure, flow, etc.) from various devices and sensors.
Thermocouple input: A thermocouple is a commonly used temperature measuring device, and the TRICONEX 4210 is able to directly receive and process the temperature signal generated by the thermocouple.
Multiple communication capabilities: The module has powerful communication functions, and can communicate with other control systems, host computers, human-machine interfaces and other devices to achieve data transmission and exchange.
Can accommodate various input, output, and hot-swappable spares: A TRICON system can contain multiple racks to accommodate appropriate combinations of input, output, and hot-swappable spares, as well as communication modules. This makes the system highly flexible and scalable.
Remote extension rack: The system can be extended to distant locations, two kilometers away from the main frame, to meet the needs of remote control and monitoring.
Security Risk Management: The TRICONEX 4210 has passed stringent security and cyber security certifications such as tuV Rheinrhei certification, IEC 62443-4-2 Security Level 1 (SL1) and IEC 61508 System Capability 3 (SC3). As a result, it can be used in safety Integrity Level 3 (SIL3) safety-related applications to meet stringent safety, cybersecurity, risk mitigation and continuous operation requirements in oil and gas, refining, petrochemical, power and other high hazard and high-risk industries.
Taken together, the TRICONEX 4210 is a powerful, safe and reliable control system for a wide range of industrial automation and process control applications.

Main Processor Modules Model 3008 Main Processors (MP) are available for Tricon v9.6 and later systems. For detailed specifications, see the Planning and Installation Guide for Tricon Systems. Three MPs must be installed in the Main Chassis of every Tricon system. Each MP independently communicates with its I/O subsystem and executes the user-written control program. Sequence of Events (SOE) and Time Synchronization During each scan, the MPs inspect designated discrete variables for state changes known as events. When an event occurs, the MPs save the current variable state and time stamp in the buffer of an SOE block. If multiple Tricon systems are connected by means of NCMs, the time synchronization capability ensures a consistent time base for effective SOE time-stamping. See page 72 for more information. Diagnostics Extensive diagnostics validate the health of each MP, I/O module and communication channel. Transient faults are recorded and masked by the hardware majority-voting circuit. Persistent faults are diagnosed and the errant module is hot-replaced. MP diagnostics perform these tasks: • Verify fixed-program memory and static RAM • Test all basic processor and floatingpoint instructions and operating modes • Validate user memory by means of the TriBus hardware-voting circuitry • Verify the shared memory interface with each I/O communication processor and channel • Verify handshake and interrupt signals between the CPU, each I/O communication processor and channel • Check each I/O communication processor and channel microprocessor, ROM, shared memory access and loopback of RS485 transceivers • Verify the TriClock and TriBus interfaces
