The difference between embedded and standard configuration software
This paper briefly introduces the main functions and application modes of the embedded version of the configuration software, and compares it with the standard version of the configuration software to get the difference between the two. Human-machine interface products, often referred to as "touch screens", contain HMI hardware and corresponding embedded version configuration software. In general, different manufacturers' HMI hardware uses different embedded version configuration software, and the main types of devices connected are PLC. The human-machine interface product of industrial control configuration software, this configuration software can greatly shorten the time for embedded products to be put on the market, and the product has rich man-machine interface, embedded WEB and control logic function according to IEC61131-3. And can store a considerable amount of historical data, partially completing the functions of the on-site workstation-level computer. Here are some examples of applications in different industries: l, manufacturing and process control: man-machine operation panel, control machine tool, motor drive, test equipment, environmental monitoring, transmission and distribution equipment, refinery equipment, remote unmanned acquisition and monitoring station; 2, medical and health equipment: X-ray machine, CT, medical management system, ward monitoring system; 3. Building automation and commercial retail outlets, commercial POS, security monitoring equipment; 4, office equipment and information appliances, set-top boxes, mobile phone embedded systems, program-controlled telephones; 5. Networked configurable devices. To sum up, we can give the application mode of embedded configuration software in industrial process. The HMI component of the application software, based on Windows CE, can obtain the operation and monitoring data of the field controller through the network service on the platform, and of course there are some other HMI extension components to complete specific functions (such as trend, history, etc.). The Internet component in the embedded system can publish the designed HMI interface to the Internet through its embedded Web service program for the operator to monitor through the browser, while the logic and process control components are based on the field level with real-time operation. The controller of the system uses IEC61131-3 to complete the embedded control function. In general, embedded industrial automation configuration software is an embedded application software for embedded systems with network functions (including Internet service functions). Embedded systems refer to embedded devices and products. A device with intelligence (ie, a microprocessor or microcontroller) connected to the network. The embedded configuration software is divided into a development system and a running system. The development environment of the embedded configuration software generally runs on a Windows operating system with a good human-machine interface, and the operating environment can be based on a variety of embedded operating systems such as Windows CE, DeltaOS, NT Embedded and LINUX and Dos, and even directly Supporting specific CPUs, the operating system of the embedded automation configuration software is mostly a component-type scalable configuration structure, which generally includes: human-machine interface HMI components (including historical data browsing, trend graphs and other optional modules), historical data recording components, networks Communication components, Internet components, Control logic and process control components, and real-time kernels. The standard version configuration software is a general-purpose tool software product running on the PC hardware platform and the Windows operating system, and can also form an HMI product together with a PC or an industrial computer. The standard configuration software supports a wide variety of devices, such as various PLCs, PC boards, meters, inverters, modules, etc., and because of the powerful performance of the PC's hardware platform (mainly in terms of speed and storage capacity), The standard version of the configuration software is also much more powerful and suitable for use in large monitoring systems. In addition, the embedded configuration software is provided free of charge with hardware (except Europe and the United States), and the standard version configuration software collects money by I/O points.
