Programming of open distributed industrial systems based on the international standard IEC 61499

Today, collaboration in software development and open architectures is changing the fundamental structure of business and reshaping the way organisations operate in a highly competitive environment, forcing them to rethink strategies. Organisations that previously created proprietary systems are beginning to develop open source products to expand the boundaries of the industries in which they operate. In a globalised world, open integrated control systems are becoming increasingly important. Their main goal is to create a balanced, efficient and functional system that integrates various aspects into a coherent whole. The article shows the advantages and disadvantages of using a new approach to programming logic systems based on the international standard IEC 61499 in the field of industrial automation of technological processes. The article analyses basic principles of the IEC 61499 standard, as well as general provisions with the OPAS standard. It also demonstrates a prototype of the control system for the model of the furnace P-101 according to IEC 61499. And provides time characteristics of the software based on IEC 61499 for real-time operating systems.
