It has the characteristics of high reliability, open system, powerful functions and easy maintenance. Control station scale: analog input and output AIO: 512, or digital input and output DIO: 1024; the system supports 32 control stations, then the system scale: AIO: 16384, or DIO: 32768.
(1) High reliability
Hardware redundancy design: hot standby redundancy of power supply modules, support dual grid input, and overvoltage and overcurrent protection; control network and system network both adopt dual redundancy; control module dual redundancy, zero switching time , to ensure control continuity; the system has built-in input voting algorithms, output voting algorithms, input and output self-test and fault reporting mechanisms for all switching and analog quantities, without user programming, as long as the configuration configuration can automatically realize redundant design;
High-reliability I/O module: point-to-point isolation, point-to-point isolation, point-to-point power distribution, and online point-to-point replacement, which can meet the requirements of nuclear power, emergency shutdown and other high-reliability and high-safety fields;
Intelligent design of components: I/O modules, I/O modules, control modules, and communication modules are all equipped with microprocessors or multiprocessors, which support module self-diagnosis, fault isolation, online plug-in, and online maintenance;
Intelligent conditioning technology: support analog (voltage/current/thermal resistance/thermocouple) universal input, software configuration type, full-scale high-precision, lossless digital transmission, self-diagnosis and self-calibration, adjustment-free and maintenance-free;
Electromagnetic compatibility design: anti-transient fast group pulse interference, signal terminal 1000V, power supply terminal 2000V; radio frequency interference suppression, transmission power 5W/0.5m; low power consumption design, no forced heat dissipation;
Operation security design: real-time data power-off retention, redundancy check, fast recovery, to ensure system information security;
Manufacturing quality control: strict component purchase, inspection, aging, and screening work; high-temperature aging of parts for 72 hours; comprehensive testing of the whole machine and continuous operation assessment for 120 hours; strictly follow the international "ISO9001 quality assurance system" and implement it in system design and development , development, production and service process.
(2) System opening
All-round open design, support ActiveX, OPC, ODBC; provide direct interface with commonly used MIS database; fully realize OPC specification; provide OLE automation server interface, DDE data exchange interface, driver interface, etc. to fully open the system to users , allowing users to expand functions and play with individuality;
Configuration language conforming to IEC61131-3 standard, including function block diagram FBD (Functional Block Diagram), ladder diagram LD (Ladder Diagram), SFC, structured text ST (Structured Text), IL, etc.;
Based on modular system hardware, open software platform, and specialized application software, it can be flexibly integrated and can be expanded horizontally or vertically according to needs; it can be used in chemical, pharmaceutical, building materials, light industry, fertilizer, urban engineering and other industries It can also be used for the control of medium-sized and combined devices in industries such as electric power, petroleum, and metallurgy.
(3) powerful
Support integrated development environment and offline and online programming, support global and unified engineering real-time database, support database online editing, deletion, and addition; real-time data 100,000 points, historical data 100,000 points; support massive historical data records, support trend charts, statistical tables, Data analysis components, etc. conduct on-site abnormal cause analysis;
Supports online configuration and online debugging of control strategies, supports single-cycle and single-step debugging of algorithms; supports simulation based on virtual control stations for testing control strategies.
(4) Easy maintenance
The IO module is equipped with a combination of industrial terminal blocks, canceling the machine cage, the bottom plate of the machine cage, the terminal board and its connecting cables, and the internal interconnection of the cabinet is standardized, so that "service begins with the terminal", which is convenient for users to use and maintain;
Support module, module, network self-diagnosis, module can be hot plugged, online repair, easy maintenance;
The modules are intelligent, multi-functional, less in type, easy to maintain, eliminate configuration waste and reduce spare parts;
The analog input type and digital input and output mode can be set by software, which is convenient for type selection and modification;
Remote technical support, providing timely and rapid system guidance, training, and maintenance services.
