The system scale has strong scalability. The single system supports 1 to 100 control stations and 100 operation stations at most. Each control

The station can support thousands of i/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is all metal enclosure, which can withstand the most

Harsh industrial environment. The equipment can be installed in the cabinet or on the wall. The system complies with all current EMC standards and has CE standards

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 ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.

PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination

Discussion.

The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard

In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control

All schemes can be realized by the combination of these function blocks.

The function blocks provided by the system mainly fall into the following categories:

Analog quantity processing

Digital quantity processing

Loop adjustment

Logical sequence
