 DCS系统-HOLLiAS MACS-K集散控制系统


1、 DCS System - Technical Characteristics of OLLiAS MACS-K Distributed Control System

1. Openness

The DCS system is no longer a closed system. The MACS series can easily integrate third-party systems and devices seamlessly through configuration without the need to change system programs. Supports commonly used international fieldbuses such as PROFIBUS/HART/MODBUS, making it easy to add third-party devices such as smart meters, PLCs, and inverters. Provide standard software interfaces such as OPC/DDE/ODBC for direct data exchange with third-party applications.

2. Informationization

The DCS system has surpassed the positioning of a traditional control system. The MACS series organically integrates factory and process management to significantly improve the production efficiency of enterprises.

Seamless integration of Manufacturing Execution System (MES) to achieve organic integration of control information and production management information.

Seamless integration of equipment management functionality (AMS) enables fully electronic information management and maintenance of factory equipment.

Can connect to common enterprise management systems (ERP), making the on-site control layer a transparent coverage area for enterprise management.

It can support remote access and browsing based on the Internet, and even if you are in a different location, process information can be kept up-to-date at all times.

3. Intelligentization

All sub components of the DCS system have been intelligentized. The components of the MACS series are coordinated and controlled through all digital information.

Each I/O is equipped with a CPU chip to achieve I/O channel level fault diagnosis. Each component can achieve self diagnosis and automatic alarm.

3. Miniaturization

The miniaturization of DCS systems is the trend. The MACS series adopts a low-power design, greatly promoting the miniaturization of the system.

The typical power consumption of the main controller is around 6W, without the need for any fan cooling, and the volume is reduced to one tenth of that of the third-generation imported DCS main controller.

The typical self power consumption of I/O modules is around 2W, with a significant reduction in size and further improvement in reliability.

4. High reliability

The design concept of DCS system is closer to safety system. The MACS series widely adopts technologies and devices that are only used in security protection systems.

Adopting deterministic real-time industrial Ethernet protocol, no data collision occurs regardless of changes in communication load, ensuring the reliability of the system network.

Using information redundancy technology to achieve data error correction. Adopting data encryption technology to ensure the blocking of illegal data access. Adopting fail safe design techniques to ensure that channels remain in a safe state in the event of a failure. Adopting international secure coding standards for software development. The software testing code coverage rate reaches 100%. Significantly improve the self diagnostic coverage of the system.
