Annals.
Industrial “DCS system design purpose: the most economical engineering investment and the most powerful control function.
Industria1 “five features of DCS system:
1、 The comprehensive control system integrates DCS & PLC & field bus;
2、 RISC superscalar high-speed CPU with super performance;
3. High reliability, strict industrial application practice, and application performance of more than 1000 sets in China;
4、 Good openness, flexibility and expansibility;
5、 Easy engineering, friendly interface and simple maintenance;
2. Industria1 “system communication
Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries
International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and network topology can be selected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize
