Industrial Automatic Control Systems and Controllers Annotation << Back Programmable Logic Controllers Timers Features of Use V.A. Holopov This article is about software and hardware timers profi t in automated technological control systems development using programmable logical controllers. Carried out analysis showed the system programming complexity requiring decent amount of timers. This brings the system’s speed and system’s quality problems. The article raises the development method for time intervals intense defi nition problem using intense generator program modules. Keywords: control system; software and hardware timers; programmable logic controllers. Contacts: E-mail: holopov@gmail.com Pp. 46-49.
