The Application Director is one of several platform views. You use it to start or stop a station in any NiagaraAX 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.

Starting in build 3.6.44, the Application Director also applies to a Workbench platform connection to a JACE-603 or JACE-645 controller configured for Niagara R2. See the “Application Director” section in the document Retrofit Board Niagara R2 Install and Startup Guide for related details.

As shown in Figure 6, the Application Director is split into three main areas:

In the Application Director for any JACE, the “installed applications” area should show (at most) only one station, as shown in Figure 6. However, the Application Director for a PC platform (Supervisor, NiagaraAX engineering workstation) may show multiple stations, as shown in Figure 7.

Prior to AX-3.6, the Application Director could show a maximum of 32 stations—regardless if more stations were under the host’s stations directory. Starting in AX-3.6, the Application Director was changed to allow access to all stations, even if over 32.
