Application Director

The Application Director is one of several platform views. You use it to start or stop a station in any Niagara host (whether a remote JACE or a local or remote Supervisor PC), as well as see station output for troubleshooting purposes. From the Application Director, you also define a station’s “restart” settings, plus have access to other station actions.

As shown above, the Application Director is split into three main areas:

  • Installed applications (stations) — at top
  • Application output — main area

    Related are log levels defined for the station. See “Station log levels (DebugService)”.

  • Application and output controls — right-side checkboxes and buttons
     
    NOTE: In the Application Director for any JACE, the “installed applications” area should show (at most) only one station, as shown above. However, the Application Director for a Windows platform ( Supervisor, or engineering workstation) may show more than one station, as shown below.

    Even if a Windows platform is licensed for more than one station, running multiple stations at the same time requires you to use non-default ports for all but one of them, in order to avoid port binding issues. For example, use a Fox and Foxs port other than 1911 or 3011 respectively, or Http and Https port other than 80 or 443 respectively.
