SEM246 – Automation Studio Workshop:IEC 61131-3 Text-based Programming with ST

Beskrivning

The IEC 61131-3 programming languages provide standardized access to PLC programming. Simple yet powerful language constructs facilitate the programming of a variety of control systems.

Learning objectives and content

Overview of programming languages based on IEC 61131-3IEC 61131-3 is the only valid international standard for programming languages used on PLCs. In addition to Sequential Function Chart, it defines other programming languages such as Ladder Diagram, Instruction List, Structured Text and Function Block Diagram.
