The Discover feature in manager views for Niagara proxy points, histories, and schedules, was enhanced starting in AX-3.5, such that discovery is essentially performed by the station you have opened in Workbench. Previously, such a discovery initiated a Fox connection directly between Workbench and the target remote station—you may have noticed another Fox station (connection) node in the Nav tree.
Typically, you perform operations like this from an opened Supervisor station.
This discovery enhancement solves the following possible issues:
-
Firewalls allow station-to-station connections, but block Workbench-to-remote station connections.
-
Branding restrictions, for example where “appliances” allow a station-to-station connection, but prevent direct Workbench-to-remote station connection.
In addition, this change lets you perform discovery of Niagara proxy points, histories, and schedules using browser access, that is, “Web Workbench”. Prior to AX-3.5, an error message resulted if this was attempted.
Note the following about these discovery enhancements:
-
No related changes are visible in the various manager views, such as Niagara Point Manager, Niagara History Import Manager, Niagara Schedule Import Manager, and so on.
-
Access to discoveries in the endpoint (target) station requires station login credentials. If that station has an account with the same credentials as the account you used to open the current (Supervisor) station, the discovery process starts immediately, without login.
If those login credentials fail, the Discover presents a login dialog. Again, you enter the login credentials for that endpoint (typically JACE) station.
