Online Mode

Order 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.
• The configuration settings for Display, Frame and Language can also be edited in online mode.
• As long as a visualization "reference" is not configured explicitly, the particular elements of the reference in online mode will react on inputs like those of the original visualization ("mother" of the references).
• When you switch the language ('Extras' 'Settings') this will only effect the display in online mode.
• A visualization can be printed in online mode.

For explanations on the online operation of certain visualization elements, such as trend and alarm table, please see the corresponding chapter on the configuration of the element.

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.

- The arrow keys can be used to change from a selected element to a neighbouring one in any direction.

- The <Space bar> is used to execute an activity on the selected visualization element. If the element is one which has a text output variable, a text input field will be opened which displays the text contents of the variable. Pressing the <Enter> key writes in this value.

Additional key (combinations) for the online operation can be defined in the configuration dialog 'Keyboard usage'. There also the keys <Tab>, <Space> and <Enter> can get assigned another functions than the above described standards.

The individual elements of references behave in Online mode identically to the corresponding ones in the visualization that is referenced. They will therefore react the same way as individual elements to inputs and operation by mouse and keyboard; the display of tooltips in references is also element-dependent. When processing the element list, as for instance when jumping from one input element to the next using the tabulator, the processing of all individual elements of a reference proceeds from the location of the reference in the element list before jumping to the next element of the list.

'File' 'Print' in online mode

'File' 'Print' is used to print out the contents of the visualization window in online mode. Visualizations which stretch over the border of the window can lead to inconsistencies particularly when there are moving elements in the visualization
