Configure general WindowViewer properties

You can configure a set of general properties that determine the characteristics of WindowViewer as it runs an InTouch application. After you modify these general properties, you must restart WindowViewer for your changes to become effective.

Note: Close WindowViewer before changing the Regional Formats of the Operating System.

1. Open WindowMaker.

2. On the File menu, select Configure, and then select WindowViewer.

   The WindowViewer configuration screen appears.

   

3. On the Preferences tab, in the WindowViewer Startup section, do the following:

   • Select the Start up as Icon check box if you want WindowViewer to start up minimized.

   • Select the Enable tag viewer check box to allow the Tag Viewer application to be started at run time. The Tag Viewer allows you to watch and monitor tags and modify tag values at run time. For details, see Enable Tag Viewer in AVEVA™ InTouch HMI Application Run Time.

   • In the Minimum access level box, type the minimum security access level required to run the Tag Viewer application. The value must be between 0 and 9999. For details, see Enable Tag Viewer in AVEVA™ InTouch HMI Application Run Time.

4. In the Inactivity in secs section, set warning and time-out periods for operator inactivity.

   For more information about setting warning and time-out periods, see Configuring an Inactivity Time-Out in AVEVA™ InTouch HMI Management.

5. In the Blink frequency in msec section, type the interval length in milliseconds for your Slow, Medium, and Fast blink animation links.

6. In the I/O area, do the following:

   • In the Retry Initiates box, type the number of seconds to wait before the InTouch application retries connecting to an I/O Server after a failed connection attempt. The I/O Retry Initiates box has no effect when InTouch can successfully connect to the I/O server the first time.

   • Select the Start local servers check box if you want a dialog box to appear when you start WindowViewer and the I/O Server you are trying to communicate with is not running.

   • Select the Reinitialize default check box if you want to reinitialize Access Names with their default settings. Current values assigned to Access Names are ignored and they are reinitialized with their original settings.

7. In the Transfer to WindowMaker area, do the following:

   • Select the Close window viewer check box if you want WindowViewer to automatically close when you start WindowMaker.

     When you select this option, the Close on Transfer to WindowViewer option located on the WindowMaker configuration screen is automatically selected too. If memory is not an issue, and you are using the fast switch to move between WindowViewer and WindowMaker, this option should be cleared.

   • Select the Close all open windows check box if you want all open windows to close automatically when you transfer from WindowViewer to WindowMaker.

8. In the Time/Timer Control in msec area, do the following:

   • In the Tick interval box, type the interval that the InTouch HMI uses to check its internal timers.

     This interval determines when Application While Running, Window While Showing, Condition While On True/On False, Key and Touch Pushbutton Action While Down QuickScripts can be started.

     This option sets the value for TimerTickInterval parameter in the INTOUCH.ini file. You should set the Tick Interval no longer than 50 msec for a script scheduled to run every 100 msec. On computers running Windows XP or Windows 2003, the lower tick interval is 10 msec.

   • In the Update for time variables box, type the interval in milliseconds that time is updated for system tags like $Msec, $Second, or $Minute.

     We recommend that you use the default setting of 1000 milliseconds. Setting this option to zero prevents time variables from being updated.

9. In the Miscellaneous area, do the following:

   • Select Beep when objects touched if you want the InTouch application to emit a beep sound when operators select touch-sensitive objects on a window.

   • Select Debug scripts if you want a message to be written to the Logger each time a QuickScript runs.

     If you select Debug from the Window Configuration property sheet, you can switch QuickScript logging on and off from WindowViewer's Special menu.

   • Select Update all trends "fast" if you want your trend objects to be updated more quickly.

     Select this option only if no objects overlap run-time trends on the application window. If you select this option and any object overlaps a trend, the object can be drawn incorrectly.

   • Select the Use old sendkeys check box if you are using an international application developed with InTouch version 3.26 or earlier.

10. In the Hotlinks area, do the following:

    • Select the Show halo around Hotlink check box if you want an object on the run time screen to be highlighted when the user moves the cursor over it.

    • If you want a halo around Active X controls, select the Show halo around ActiveX control check box.

    • Select the Halo follows object shape check box if you want a highlight halo around the contours of an object when the user moves the cursor over it.

11. In the Keyboard area, select the type of keyboard you want to use, if any.

    For more information about setting keyboard options in WindowViewer, See Animate objects in AVEVA™ InTouch HMI Application Development.

12. Select the Allow decimal notation checkbox, to allow only decimal values during runtime, and restrict non-numeric characters. (The Allow decimal notation option not been tested on a non-English language Operating System.)

13. In the Alpha numeric keyboard and Numeric keyboard areas, configure the X, Y location as well as the Width and Height values.

14. Select Save.
