Niagara proxy point discovery was enhanced starting in AX-3.5 to permit operations that were previously blocked or unavailable.
For details, see Niagara Discover enhancements.
Niagara point discovery launches the Bql Query Builder, where you specify the root level of component hierarchy in the remote station to begin the discover.
Component type filters are available in that dialog too—for details, see Bql Query Builder.
Starting in AX-3.4, the Niagara Point Manager was enhanced with an option for point discovery to a tunnel-accessible only station, using a “Tunnel Discovery Mode”. Special indication of this mode being active is provided by a banner at the top of the Point Manager, as shown in Figure 88.
This feature is not required when connecting to an AX-3.5 or later station and doing point discoveries (and other discoveries).
For related details, see Niagara Discover enhancements.However, if working with an AX-3.4 station (even if using a more recent Workbench), you may need to use this feature for
Point discovery for stations accessible only via Fox tunneling. Otherwise, Workbench needs a direct Fox connection for point
discovery, that is, be on same LAN.In this case, you can toggle into this “Tunnel Discovery Mode” to perform a Niagara point
discovery.
You enable/disable this feature using a pull-down toggle option on the bottom button, also available on the Manager menu and toolbar.
