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.
- Differences between textual and graphical programming languages
- Working with Structured Text (ST)
- Basic constructs
- Decisions
- Loops
- Working with arrays
- Step switching mechanisms
- Calling function blocks
- Calling actions
- Creating simple programs independently
- Working with another programming language (optional)
Tasks include
- Participants will use high-level programming languages.
- Participants will implement programs in accordance with IEC 61131-3.
- Participants will program sequences for machine controls.
- Participants will extend existing programs.
