2 - The Visualization Editor in CoDeSys

List of placeholders for replacing a placeholder in a visualization instance

Column Placeholder – like described above – shows all placeholders which have been defined for the primary visualization object. If additionally a selection of possible replacements had been defined, this list will now be available in column 'Replacement'. Select one of the entries to replace the placeholder in the present instance. If no replacements have been pre-defined then you can manually enter an expression or variable. For this purpose perform a mouse-click on the field in column Replacement to open an editor field.

2.8Visualization in Online Mode...

Regard the following items concerning a visualization in online mode:

oOrder of evaluation:

Dynamically defined element properties (by variables) will overwrite the (static) base settings defined by options in the configuration dialogs.

If an element property is defined by a "normal" project variable as well as by the component of a structure variable (Programability), then primarily the value of the project variable will be regarded.

A visualization can be configured in that way that in online mode it can be operated solely by inputs via keyboard. This is an important feature especially for using the visualization with CoDeSys HMI, as Targetor as Web-Visualization.

oThe configuration settings for Display, Frame and Language can also be edited in online mode.

oAs long as a visualization "instance" is not configured explicitly, the particular elements of the instance in online mode will react on inputs like those of the original visualization ("mother" of the instances).

oWhen you switch the language ('Extras' 'Settings') this will only effect the display in online mode.

o A visualization can be printed in online mode.

Operation over the keyboard - in online mode

In order to get independent from the mouse or a touch screen, it is useful to configure a visualization in a way that allows pure keyboard operation:

Per default the following key (combinations) will work in online mode anyway (no special configuration necessary):

Pressing the <Tabulator> key selects the first element in the element list for which an input is configured. Each subsequent pressing of the key moves one to the next element in the list. Pressing the key while keeping the <Shift> key depressed selects the previous element.
