PLC technology development and international standard IEC61131

gkong news on May 1, the cooperation between industrial chains and enterprises was strengthened. On May 2, the seminar on PLC technology development and IEC international standard jointly sponsored by China electromechanical integration technology application Association and PLCopen China was successfully held in Beijing

eelco van der warl, executive chairman of PLCopen international organization, Peng Yu, chairman of PLCopen China organization, and heads of relevant units and enterprise representatives such as German Beifu, Rockwell Automation and German Covey software attended the seminar

Eelco van der warl, executive chairman of PLCopen international, made a report. At the seminar, the participating experts made an in-depth discussion on the development and future development trend of PLC and IEC technology

Eelco van der warl, the chairman of PLCopen International Organization for the integration of sales and after-sales, introduced IEC international standards and their promotion. IEC international standard is the only global standard for industrial control programming language, which has had an important impact in the field of industrial control. It has been accepted by more and more manufacturers and customers all over the world, and has become the de facto standard for programming systems of DCS, PLC, FCS, IPC, CNC, and SCADA. This standard has played an important role in promoting the development of PLC software technology, and even the development of the whole industrial control software technology. Pw4084 and pw4168 engines adopt pr500 epoxy resin to manufacture fan OGV

with the vigorous development of digitalization, informatization and intellectualization in all fields of the world, the demand for automatic components, single machines, devices to set experimental parameters and systems in various fields such as industry and civil use, production and consumption is increasing, and the requirements for PLC functions and technology are also getting higher and higher. PLC is constantly adopting other new technologies to cope with the impact brought by the gradual reduction of market share

At the seminar, Peng Yu, chairman of PLCopen China organization, said that with the widespread acceptance of IEC standards, the increasingly severe economic competition environment, and the rising development costs and engineering costs of industrial control software, the manufacturing industry hopes to exchange its programs, function/function block libraries and engineering projects between different software development environments. The PLC system adopts fdt/dtm to introduce the asset equipment management function, and seamlessly utilizes the data and functions of all instrument equipment or equipment in the system for the whole automation system

Wang Ningqiang, technical director of Beifu Beijing Branch in Germany, introduced TwinCAT control system based on IEC international standard. The system is based on the integrated automatic control software package, including development tools and real-time core. It can be applied to sequence control, motion control and technical functions. It is suitable for different hardware platforms and supports all IEC languages (IL, St, FBD, LD, SFC)

then, Wang Guangye, product manager of Rockwell Automation, introduced the new progress of Rockwell Automation PAC and its programming language. Liang enquan of German Covey Software Co., Ltd. described how to quickly develop IEC based controllers
