Open Source PLCs and IEC 61131-3 Standard: The freedom of programming in automation
by MectIn the world of industrial automation, programming programmable logic controllers (PLCs) is a key aspect of ensuring the efficiency and productivity of machines and plants. However, the choice of programming software can be a critical factor, as it can affect programming freedom and compatibility with industry standards.
In this context, the open source PLC solution can offer great programming freedom, allowing developers to customize and adapt the software to the specific needs of the application. However, it is important to ensure that the open source PLC solution is compatible with industry standards, such as IEC 61131-3, to ensure interoperability and compatibility with other systems and devices.
The IEC 61131-3 standard: a guarantee of compatibility
The IEC 61131-3 standard is a set of rules and specifications that define the programming of programmable logic controllers (PLCs) and associated development environments. This standard was developed to ensure compatibility and interoperability between different PLC systems and devices, regardless of manufacturer or model.
The IEC 61131-3 standard defines five programming languages:
- Ladder Diagram (LD): a graphical programming language that uses symbols and diagrams to represent logical functions.
- Function Block Diagram (FBD): a graphical programming language that uses functional blocks to represent logical functions.
- Structured Text (ST): a textual programming language that uses a syntax similar to that of traditional programming languages.
- Sequential Function Chart (SFC): a graphical programming language that uses flowcharts to represent logical functions.
- Instruction List (IL): a textual programming language that uses a syntax similar to assembly language.
