About ord substitution overrides

Apart from ord substitutions to image files and real-time values, other ord changes may be necessary, typically “hyperlink” or bound ord types that may not virtualize correctly (or in context) at the Supervisor station. For example, consider a “Current Weather View” Px widget bound to a WeatherReport component in the JACE station (Figure 36).

In the Figure 36 example, when viewing this on the Supervisor, instead of the original binding (which will not visualize correctly), the desired target is an equivalent WeatherReport component in the Supervisor station. The PxViewTag property sheet provides a View control and dialog that you can use to override such ords to different values.

From the PxViewTag property sheet, click the View control for a popup View dialog, then click the Choose from Px button for a Choose from Px dialog, listing ords you can check one or more to override.

As shown in Figure 37, a checked ord provides an Edit dialog showing the “Old ORD”, along with a “New ORD” field, in which you can manually type a new ord. This new ord should be relative to the Supervisor station (and not the currently open JACE).

NoteIn this case, note that the drop-down control to select the Component Chooser, File Ord Chooser, and so on, is relative to the opened JACE station—and likely not helpful in this case.

After clicking OK to finish the override edit, the overridden ord appears in the View dialog (Figure 34).

Such overrides are now part of this PxViewTag configuration, which you can re-edit to add, delete, or modify again before any Join operation.

Ords that do not virtualize

In addition to ords with a hyperlink, these other types of ords can cause issues in PxViewTags:

  • Ords that contain a BQL query — these cannot resolve correctly.

  • Ords to Workbench views on components in a remote station, for example the Current Weather View example shown in Figure 36. Virtual components do not provide access to the Workbench views associated with the source components.
