SCADA. v. t. e. A programmable logic controller ( PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
IEC 61131-3. IEC 61131-3 is the third part (of 10) of the international standard IEC 61131 for programmable logic controllers. It was first published in December 1993 [ 1] by the IEC; the current (third) edition was published in February 2013. [ 2]
Sequential function chart ( SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems, and was based on GRAFCET [ fr] (itself based on binary Petri nets [ 1][ 2] ).
Ladder logic has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs) used in industrial control applications.
Guile. Emacs Lisp. JavaScript and some dialects, e.g., JScript. Lua (embedded in many games) OpenCL (extension of C and C++ to use the GPU and parallel extensions of the CPU) OptimJ (extension of Java with language support for writing optimization models and powerful abstractions for bulk data processing) Perl.
IEC 61131 is an IEC standard for programmable controllers. It was first published in 1993; [ 1] the current (third) edition dates from 2013. [ 2] It was known as IEC 1131 before the change in numbering system by IEC. The parts of the IEC 61131 standard are prepared and maintained by working group 7, programmable control systems, of subcommittee ...
The five programming languages for application programming defined in the IEC 61131-3 are available in the CODESYS development environment. IL (instruction list) is an assembler-like programming language. The IEC 61131-3 user organization PLCopen has declared this language as “deprecated”, which means it shall not be used for new projects ...
Structured text, abbreviated as ST or STX, is one of the five languages supported by the IEC 61131-3 standard, designed for programmable logic controllers (PLCs). [ 1][ 2] It is a high level language that is block structured and syntactically resembles Pascal, on which it is based. [ 3] All of the languages share IEC61131 Common Elements.
