Programming Languages and Editors¶

You program a POU in each case in the editor for the implementation language that you selected when creating the POU. CODESYS offers a text editor for ST and graphic editors for SFC, FBD/LD/IL and CFC.

The editor opens with a double-click on the POU in the device tree or in the POUs view.

Each of the programming language editors consists of two sub-windows:

• In the upper part you make declarations in the “declaration editor”, in text or tabular form depending on the setting.
• In the lower part you insert the implementation code in the respective language.

You can configure the display and the behavior of each editor project-wide on the associated tab of the CODESYS options.
