Industrial Automatic Control Systems and Controllers Annotation << Back Principles of Programming in the PCS Language FBD B.G. Sevastyanov, D.B. Sevastyanov The paper summarizes the basic principles of the implementation of the automatic control system. To improve the effectiveness of the development and operation of the control system programmers implementing programs in the languages FBD and CFC, must adhere to certain principles. The authors have taken as a basis for the work of V.M. Glushkov and his proposed principles. Based on the experience in implementing various automated systems offered on the principles of programming languages FBD and CFC for different controllers. The article reveals the essence of the principles: uniformity in encryption, numbering and location of algorithmic blocks; non-rigid numbering algorithmic blocks; middleware and other terminals. The principles of implementation of the automatic control system offers a common ideology of building systems and can be applied to most of the problems. Keywords: process control; programming principles; programming in languages FBD and CFC; software quality controllers. Contacts: E-mail: seva-boris@yandex.ru Pp. 22-27.
