What are the programming languages supported with SoMachine V4.3?

Issue:

Understanding the programming languages supported by SoMachine.

Product Line:

SoMachine v4.3

Cause:

Users may be unfamiliar with the programming languages available in SoMachine

Resolution:

SoMachine / Codesys is an open international standard IEC 61131-3  for programmable logic controllers.

The following programming languages are supported.
-IL (instruction list) is an assembler like programming language (Is now deprecated but available for backward compatibility)
-ST (structured text) is similar to programming in Pascal or C
-LD (ladder diagram) enables the programmer to virtually combine relay contacts and coils
-FBD (function block diagram) enables the user to rapidly program both Boolean and analogue expressions
-SFC (sequential function chart) is convenient for programming sequential processes and flows


Additional graphical editor available in CODESYS not defined in the IEC standard.
CFC (Continuous Function Chart) is a sort of freehand FBD editor. Other than in the network-oriented FBD editor where the connections between inputs, operators and outputs are set automatically they have to be drawn by the programmer. All boxes can be placed freely which makes it possible to program feedback loops without interim variables.
