Save Changes between Page Transitions (Runtime)

Using Plant SCADA run time, if you modify the Process Analyst (for example, changing the timespan of a pen) and move off the page, your changes will be lost. This behavior is not always what you want, so Graphics Builder provides an option Persist ActiveX data between page transitions to save the state of an ActiveX control when you switch between pages.

Enabling this option causes Plant SCADA to write a temporary file to the Plant SCADA Data directory in the format of <Event class>.stg whenever you leave a page that contains an ActiveX object (for example, the Process Analyst). When you reenter the page, Plant SCADA looks for that same file and, if found, will load the settings from it. These files only exist while Plant SCADA run time is running. When you shut down Plant SCADA, the temporary *.stg files are deleted.

To save between page transitions:

1. Double-click the Process Analyst ActiveX control you want to change. The Properties dialog box appears.

2. Click the Access tab.

3. Click the Identification tab. The Identification panel appears.

   

4. In the Persistence area, select the Persist ActiveX data between page transitions check box, and then click Apply.
