TMR processor module Features: ◆ Based on the triplex processor system, all the important internal circuits are triplex fault-tolerant design; ◆ The main control chip adopts 64-bit 100MHZ Motorola RISC microprocessor (600 series); ◆ Small and light, the TRUSTED system is only 1/3 of the size and 1/14 of the weight of other TMR systems; ◆ Industry advanced industrial brain and bus system, system response time within 50ms (50 TMR points); ◆ Unlimited online modification; ◆ Complete I/O line monitoring function, support IO module online monitoring function, comprehensive monitoring of the status of the field signal; ◆ Availability of SIL3 safety system, up to 5 fault zones, fully compliant with TUV standard 3-2-0 degradation mode; ◆ The industry has module environment real-time monitoring function; ◆ The industry's safety instrument system as a whole SIL3 standard solution, the use of valve 7] test software to automatically monitor the change of valve stroke, diagnose the work of the safety stop valve, to improve the safety of the entire loop; ◆ ICS Triplex technology unique hardware voting (HIFT) technology; ◆ Automatic fault isolation without performance degradation; Support module hot replacement, trouble-free troubleshooting; ◆ Support for SIL 3 certified remote expansion rack fiber connection, greatly improve the flexibility of the system; ◆ Each analog point has an independent triplex AD converter, so there are actually 120 independent AD conversions inside a 40-point triplex analog module; ◆ Support all 5 IEC61131 programming languages: ladder logic diagram, function block, structured text, instruction table and control diagram.

Common controllers in industrial control systems The Controller refers to the master command device that controls the starting, speed regulation, braking and reverse of the motor by changing the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order.  It is the "decision-making organization" that issues commands and completes the operation of coordinating and commanding the whole computer system. 1.  Programmable Logic Controller (PLC) is a special Controller, which is a digital computing electronic system designed for industrial applications. 2, Programmable Automation controller (PAC) is defined as: supported by a lightweight control engine, and use the same development tool for a variety of applications. 3.  The fundamental difference between PAC and PLC lies in their different foundations.  The performance of PLC depends on special hardware, and the execution of application program is realized by special hardware chip. 4.  Remote Terminal Unit (RTU) is the electronic equipment installed in the Remote site, which is used to monitor and control the status of sensors and equipment in the Remote site.  RTU is responsible for the monitoring and control of field signals and industrial equipment, obtaining equipment data, and sending the data to the dispatching center of SCADA system. 5.  In the remote measurement and control system, RTU is the key equipment to realize remote communication, which is responsible for the uploading and transmitting of information between the central station and the measurement station.  It mainly has four functions: remote communication, telemetry, remote control and remote modulation. ◆ Remote communication function: the passive contact mode is required, that is, the input of a certain distance communication amount should be a pair of relay contacts, or is closed, or is disconnected. ◆ Telemetry function: by collecting the signals of various sensors and transmitters to obtain the physical parameters of the scene, the collected variables are stored and encoded into telemetry information, which is transmitted to the monitoring center according to the communication protocol. ◆ Remote control function: the monitoring center implements remote control on the site equipment, such as starting or shutting down a device, opening or closing a valve. ◆ Remote adjustment function: the monitoring center can adjust the working status and parameters of some equipment in the controlled station.
