IEC1131 programming language
GF_Project VX has a PLC component for configuration of the machine/system control logic. The component uses the IEC1131 programming standard to insert all of the control logics.The PLC component uses a tool called GF_Project VX Code to insert and diagnose the control part of the Automation system.The PLC component uses the functions provided by standard IEC1131-3, which creates a programming standard used by various builders and allows configuration of a control logic that exploits a series of common languages and rules.Standard IEC1131 details the rules and characteristics of all the components making up a PLC control logic.In general, standard IEC1131 describes :
- What types of data can be used
- What types of programming languages can be used
- What programming rules are used by the different types of languages
- A list of “keywords” reserved to writing/configuring a control logic
- LD (Ladder Programme)
- IL (Instruction List)
- ST (Structured text)
- SFC (Sequential Function Chart)
- FBD (Function Block Diagram)
