Industrial control refers to industrial automation control, mainly using the combination of electronics, machinery and software. It is industrial control (Factory control), or Factory Automation control (Factory automation control). It mainly refers to the use of computer technology, microelectronics technology, electrical means, so that the production and manufacturing process of the factory is more automated, efficient, accurate, and has control and visibility.
The emergence and promotion of industrial control technology has brought about the third industrial revolution, which has increased the production speed and efficiency of factories by more than 300%. These products and technologies have greatly promoted the process of manufacturing automation in China and made great contributions to the construction of China's modernization. The main core areas of industrial control are in large power stations, aerospace, dam construction, industrial temperature control heating, ceramic field has irreplaceable advantages. For example, the real-time monitoring of power grid needs to collect a large number of data values and conduct comprehensive processing, and the intervention of industrial control technology facilitates the processing of a large amount of information. The emergence of industrial control has improved the safety and accuracy of the manufacturing and construction industries, and solved the industrial needs of temperature, pressure, gas flow, and liquid flow that were originally needed. In the original need for semi-automatic and manual work evolution automation, including common air switches, pressure, flow meters, etc. Working principle of industrial control: such as the power control of the air switch, when the power of the electrical appliance is too large, the internal mechanical principle begins to run, causing the switch to automatically disconnect, so as to ensure the safety of industrial or building electricity and accurately find the short circuit source.
A kind of configuration software, such as WinCC, Kingview, InTouch, Ifix, etc., has strong functions and convenient configuration, but has a point limit, poor flexibility and high price. The second type of independent development of industrial control software can use high-level languages, such as C++,.NET and so on. Flexibility is high, but the workload is heavy and requires professional software developers.
Common configuration software in the field of industrial automation control are: InTouch, iFix, Citech, WinCC, Kingview, Controx Open, ForceControl, GE Cimplicity, RSView Supervisory Edition, Lookout, Wizcon, MCGS, etc.
1, InTouch: The InTouch software of Wonderware is the earliest configuration software that enters our country. In the late 1980s and early 1990s, InTouch software based on Windows3.1 was refreshing to us, and InTouch provided a rich library of images. However, earlier InTouch software used DDE to communicate with drivers, and performance was poor, and the latest version of InTouch7.0 has been fully based on the 32-bit Windows platform, and provides OPC support.
The Internet is a magical big network, industrial control software configuration software and big data development and software customization is also a model, here to provide the most detailed offer, if you really want to do, you can come here, the beginning of the manual number is 187, the middle is three son zero and the last is one hundred and twenty-five fifty, in accordance with the sequence of combination can be found, want to say is, Unless you want to do or know something about it, if you're just joining in, don't come.
2, iFix: Intellution started with Fix configuration software, was acquired by Emerson in 1995, and is now a wholly-owned subsidiary of Emerson Group, Fix6.x software provides industrial control personnel familiar with the concept and operation interface, and provides complete drivers (need to be purchased separately).
Intellution has named its latest product line iFiX, in which Intellution offers powerful configuration capabilities, but the new version is not fully compatible with the previous 6.x version. The original Script language was changed to VBA (Visual Basic For Application), and Microsoft's VBA development environment was integrated internally. Unfortunately, Intellution does not provide a scripting language to VBA conversion tool for version 6.1. In iFiX, Intellution's products are tightly integrated with Microsoft's operating systems and networks. Intellution is also a founding member of the OPC (OLE for Process Control) organization. iFiX's OPC components and drivers also need to be purchased separately.
3. Citech: Citech of CiT is also the first product to enter the Chinese market. Citech has a concise mode of operation, but its mode of operation is more oriented to programmers, rather than industrial users. Citech provides a scripting language similar to C for secondary development, but unlike iFix, Citech's scripting language is not object-oriented, but similar to C language, which undoubtedly increases the difficulty for users to carry out secondary development.
4, WinCC: Simens WinCC is also a complete set of configuration development environment, Simens provides C-like language scripts, including a debugging environment. WinCC has built-in OPC support and can configure distributed systems. However, the structure of WinCC is more complex, and the user is best trained by Simens to master the application of WinCC.
5, Kingview: Kingview is the first influential configuration software development company in China (most of the earlier brands have been annihilated). Kingview provides the main interface of resource Manager, and provides scripting language support with Chinese characters as keywords. Kingview also offers a variety of hardware drivers.
6, Controx (open) : Huafu Computer company Controx2000 is a full 32-bit configuration development platform, for industrial control users to provide powerful real-time curve, historical curve, alarm, data report and report functions. As the first software developer in China to join the OPC organization, Controx has built O [Industrial Electrical Network -cnelc] PC support and provides dozens of high-performance drivers. Provides an object-oriented scripting language compiler, supports plug and play of ActiveX components and plug-ins, and supports connecting to external databases via ODBC. Controx provides both network support and WevServer functionality.
7, ForceControl: Daqing 3D company ForceControl (force control) From the concept of time, force control is also one of the configuration software that has appeared earlier in China. Just because the early power control has not been widely promoted as a formal commodity, it is not known to most people. Around 1993, the first version of Power Control was formed, but at that time it was a DOS and VMS based version. Later, with the popularity of Windows3.1, a 16-bit Windows version of force control was developed. But until the birth of the Windows95 version of force control, it was mainly used for some projects within the company. The 1.0 version of force control under 32-bit has a relatively obvious advancement in the architecture, and one of its biggest characteristics is that it is based on the three-layer structure of the real distributed real-time database, and the real-time database structure can be a configurable living structure. During 1999-2000, power control has been greatly developed, and the latest version 2.0 has been greatly improved in the richness of features, ease of use, openness, and the number of I/O drivers. In the design of many links, the power control can start from the perspective of domestic users, that is, pay attention to practicality, without losing the specification of large software. In addition, the company has invested a large amount of manpower in product training, user technical support and other aspects, I believe that in a relatively short time, force control software products will form a huge impact in the industrial control software industry.

12, MCGS (Monitor and Control Generated System) is the configuration software is developed by the general state software company, a set of Windows platform, for the rapid construction and generation of the host computer monitoring system configuration software system, It runs on Microsoft Windows 95/98/Me/NT/2000 and other operating systems.
Industrial control systems are widely used in the fields of process production, power facilities, hydraulic oil and gas and transportation. The security of the traditional control system mainly depends on the secrecy of its technology, and almost no security measures are taken. With the increasing attention of enterprise management to production process data, industrial control system adopts open lnternet technology to realize interconnection with enterprise network more and more. At present, most industrial communication systems develop protocols based on commercial operating systems, and there are many loopholes in communication applications. When an industrial control system is connected to the Internet or other public networks, these vulnerabilities can be exposed to potential attackers. In addition, industrial control systems are often used to control critical infrastructure measures, and attackers will actively attack them for political or economic purposes, with a view to causing serious consequences. For example, in 2010, the Stuxnet virus swept the world, and the Bushehr nuclear power plant in Iran was delayed due to this attack. Therefore, in recent years, the information security of industrial control system has become a hot issue
