system contains about 220 functions
Algorithm library for energy blocks and a basic library with more than 200 graphic symbols and an extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to complete the configuration and debugging of process level, operation level and even fieldbus instruments, and uses the same
a global database.
The scale of the system is highly scalable, and a single-system supports 1 to a maximum of 100 control stations and 100 operating stations. each control
The station can support several thousand I/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is encapsulated in an all-metal shell, which can withstand the most
Harsh industrial environment. The device can be installed either in a cabinet or on a wall. System complies with all current EMC standards and is CE marked
Chi.
Industrial” DCS system design purpose: the most economical engineering investment, the most powerful control function.
Five features of Industria1″ DCS system:
1. All-round integrated control system, integrating DCS & PLC & Field Bus;
2. Using RISC SuperScalar high-speed CPU, with super performance;
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
