而这些数据和记录一旦经由计算机化系统(Computerized System)产生、处理或者保存等(未来会越来越多 - 这是Pharm 4.0的趋势),那么我们就可以说这个计算机化系统是direct GxP impact直接影响GxP, 需要进行Computerized System Validation计算机化系统验证。 1.定义 - 什么是 DCS & SCADA 及PLC 从大侠当年大学自动化工程课...
DCS:(Distributed Control System)采用分散控制、集中显示、分而自治、综合协调的设计原则 PLC:(programmable logical controller重要的底层控制部件具体操作与工艺控制 2.相同点 - DCS & SCADA都可以通过PLC来实现自动化控制 从大侠当年大学自动化工程课程教材《电气控制与 PLC 应用(第 4 版) 参见上图ISA95 ...
SCADA系统软件通常也称为组态软件,是上位机软件中的一种,用于数据采集与过程控制的专用软件多使用于SCADA系统和DCS系统中。国外SCADA组态软件常见的有IFIX、WinCC、InTouch。国内常见的SCADA组态软件有三维力控、北京亚控、紫金桥、巨控王、昆仑通态等。 目前国内也有新一代的基于Web的SCADA系统软件,如: 佰思杰公司的...
Maintaining the integrity and availability of PLCs, DCS, and other control system devices is important. Additionally, securing field devices like sensors and actuators, which directly interact with physical processes, is essential. Protecting the data flow between various ICS components is equally import...
DCS approach: As control logic is designed, alarming, HMI and system communications are automatically configured. One software configuration tool is used to set up one database used by all system components. As the control engineer designs the control logic, the rest of the system falls into ...
SCADA Vs Distributed Control Systems (DCS)SCADA monitoring equipment can also be seen as a system with many data elements called points. Each point is a monitor or sensor and these points can be either hard or soft. These elements ensure that control equipment operates easily in SCADA ...
Kan:SCADA systems can trace their origins to the earliest human-machine interface (HMI) on the factory floor in the early 1970s. Distributed control systems (DCS) started to have displays during that time. The first SCADA systems ran under DOS (disk operating system) and were a central gathe...
FreeSCADAis an open source SCADA system for MS Windows (2000/XP/Vista) which provides end users with flexible tools for visualization and interactive control of any industrial process. The system uses OPC servers for data collection and is developed using the C# language on .NET 3.0 platform ...
