This example project shows new visualization elements and their usage on the basis of a fire engine. In addition, the example project demonstrates the efficient programming of web visualizations for mobile devices.

This example demonstrates the use of the Recipe Manger. A recipe in CODESYS is a value set for a user-defined variable list (recipe definitions). Recipes can be used for setting and monitoring values for a specific set of variables on the PLC.

The ‘Visu Ladder Logic Editor’ allows direct programming on a PLC via the visualization.

This library contains a function block and a ladder logic editor which can be instanced by a PLC program. The function block has 8 inputs and 8 outputs and can be programed via ladder logic. An example shows the usage of the library.
