In this video, Zahraa Khalil overviews the five PLC programming languages used in programming PLC and the IEC standard, then defines the languages.
- [Instructor] PLC programming languages.…IEC 61131-3, international standard…that defines PLC programming languages and concepts.…This defines the specifications required for languages…that operates the programmable logic controllers.…Programming languages are divided into two main sections…to represent the five main programming languages,…a text-based and a graphical.…
Text-based, instruction list, structured text.…Graphical, ladder logic diagram, function block diagram,…sequential function chart.…Two common methods for PLC programming…is ladder logic and block diagram.…So the standard explains the format, the syntax,…and display for the five PLC languages available.…Each language is used and best suited…for certain types of applications.…
Learn about the components and networks involved at each level of automation: field level, control level, and management level. Explore the different devices involved, from the programmable logic controllers (PLCs) on the factory floor, to OPC software that give technicians insights into operations. Instructor Zahraa Khalil, an engineer and educator, also provides an overview of SCADA (supervisory control and data acquisition), an industrial control system architecture that enables supervision over large distances and multiple sites.
