IEC 61131-3 Editors

CoDeSys offers all editors defined in the IEC standard for application development: Structured Text (ST), Sequential Function Chart (SFC), Continuous Function Chart (CFC), Function Block Diagram (FBD), Ladder Diagram (LD) and Instruction List (IL).

All editors were especially designed to ensure optimal handling. Ideas and suggestions from experienced users are incorporated into the development process.

Some examples:

When working in FBD, LD or IL you can freely switch between these editors. This is possible both in the offline and online mode.
Language elements can either be entered directly or dragged into the editor from a tool box. Additionally, CoDeSys offers an intelligent input assistance and an extended IntelliSense functionality.
Standard language constructs (i.e. IF statements, FOR loops, variable classes etc.) can be folded and unfolded in the text editors.
Language constructs are automatically created (e.g. IF END_IF).
The SFC editor can either be used as defined in the standard or in a simplified version.
A comfortable time monitoring for steps as well as an online diagnosis functionality is also available in the SFC editor.
Steps and transitions in the SFC editor and all elements in the CFC editor can be encapsulated in macros.
Above that, CoDeSys implements numerous further functions which support the application developer in his work.
