Visualization Element ‘Check box’

Symbol:

Tag: Common controls

This element is used for setting and resetting a Boolean variable. The set state is represented by a check mark.

Element properties

Element name	Optional Tip: Assign individual names for elements so that they are found faster in the element list. Example: signal_tone_for_parts_deficit
Element type	Check box
Text ID	ID for the text in the GlobalTextList. Example: 22. The text ID cannot be modified. As soon as you specify and save a text in Texts - Text, CODESYS automatically creates an entry in the GlobalTextList and displays the ID here.

Element property ‘Position’

The position defines the location and size of the element in the visualization window. These are based on the Cartesian coordinate system. The origin is located at the upper left corner of the window. The positive horizontal x-axis runs to the right. The positive vertical y-axis runs downwards.

X	X coordinate of the upper left corner of the element Specified in pixels. Example: 10.
Y	Y coordinate of the upper left corner of the element Specified in pixels. Example: 10.
Width	Specified in pixels. Example: 150
Height	Specified in pixels. Example: 30

Note

You can also change the values by dragging the box symbols ( ) to other positions in the editor.

Element property ‘Text properties’

Individual text properties Requirement: The Individual settings text property is defined.
Horizontal alignment	Horizontal alignment of the text within the element.
