ScheduleExportTag properties

To see the tag in context, double-click the parent ScheduleImportExt descriptor ( ext) to see its property sheet, then expand the ScheduleExportTag, as shown in Figure 43.

Figure 43. ScheduleImportExt property sheet example, showing child ScheduleExportTag properties

The important property in the parent Niagara ScheduleImportExt is the following:

Supervisor Id

Location of source Supervisor’s (master) schedule, using syntax as follows:

slot:path

where path includes parent folder(s) and the name of the schedule component, for example:

slot:/Schedules/Ltg/LtgAnnex

for a schedule named “LtgAnnex” located in the “Schedules”, “Ltg” folder on the Supervisor.

If adding a new schedule, this property is initially blank—it is populated upon a successful Join.

ScheduleExportTag properties are described as follows:

Status

Read-only status of the export tag, typically “ok”, unless “disabled” (Enabled=false).
Enabled

Whether the tag will attempt an export on the next Join (true, the default) or not (false).
Supervisor Station

Reflects the NiagaraStation name for the Supervisor, and is read-only.
Station Slot Path

Parent slot path for the ScheduleExportExt on the Supervisor, read-only and fixed as the schedules slot (Schedules extension) of the NiagaraStation that represent this subordinate (JACE) station.
Override Supervisor Id

Boolean as to whether to override any existing Supervisor Id in the parent ScheduleImportExt, and use instead the NiagaraStation-relative “Override Supervisor Id Station Slot Path” value (next property). By default, this is false.

Typically, you set this to true when making an new master schedule on the Supervisor, at the location specified in the next property (relative to the NiagaraStation that represents this JACE).
Override Supervisor Id Station Slot Path

Parent folder location for the source Supervisor’s (master) schedule if “Override Supervisor Id” is set to true. The default slot path is simply “slot:”, which means the root of the NiagaraStation that represents this subordinate (JACE) station on the Supervisor.

Or, click open folder, to see the Select Parent Target dialog with station ready to expand.
You may edit the “profile.bog file” to specify a new target folder structure—see Verify and edit the Station (.bog) File for details.

When overriding the Supervisor Id, a new master schedule is created on the Supervisor in this parent folder, named the same as the (grandparent) schedule component (slave) that has this export tag. You will need to configure the master schedule in the Supervisor station.
Export Execution Time

The standard execution time selections for a Niagara ScheduleExportExt descriptor, where the default is Daily at 2:00 AM, all days of the week. Other selections include Manual or Interval.
