More information

PLC_PRG: The main program holds the variables in which the visualization writes
the values from the keypad or numpad.

Visualization: The visualization has three fields. Each displays either a numpad or a keypad when clicked.
The first one displays a numpad for integer numbers. It also uses a minimum and maximum value. The second one
inherits a numpad for real numbers. The third field displays a keypad for writing letters to a string variable.

All fields are configured with an "OnMouseClick" event in the properties editor.
