Element property ‘Absolute movement’

These properties are used for dynamically controlling the element position by means of variables. The reference point is the upper left corner of the element. In runtime mode, the entire element is moved.

Movement
X:	Variable (integer data type). Defines the X position (in pixels). Example: PLC_PRG.iPos_X. Increasing this value in runtime mode moves the element to the right.
Y:	Variable (integer data type). Defines the Y position (in pixels). Example: PLC_PRG.iPos_Y. Increasing this value in runtime mode moves the element downwards.

Element property ‘State variables’

Invisible

Variable (BOOL). Toggles the visibility of the element. TRUE: The element is not visible at runtime.

Element property ‘Control variables’

URL	URL of the web page that is displayed in the visualization. Variable (STRING or WSTRING) Example: PLC_PRG.stURL Literal in single straight quotation marks Example: 'http://de.wikipedia.org'
Show	Variable (BOOL). Example: PLC_PRG.bSetURL Controls the display of the Web browser element. If the variable contains a rising edge, then the visualization calls the web page given in URL and displays its contents in the ‘Web browser’ visualization element.
Back	Variable (BOOL). Example: PLC_PRG.bGoBack Controls the back navigation in the Web browser. If the variable has a rising edge, then the visualization displays the contents of the previously displayed page.
Forward	Variable (BOOL). Example: PLC_PRG.bGoForward Controls the forward navigation in the Web browser. If the variable has a rising edge, then the visualization displays the contents of the previously displayed page.

Element property ‘Access rights’

Requirement: User management is set up for the visualization.

Access rights

Opens the Access rights dialog box for changing the access rights for the element. Status messages: Not set. All rights.: Access rights for all user groups : operable Rights are assigned: limited rights: Access is restricted for at least one group.
