When you enable the JoinProfile (of the NiagaraStation for the Supervisor) on the JACE station, a new folder with a station profile.bog file is automatically created in the JACE station’s file space. You routinely edit and save this bog file, as it can determine property values of the NiagaraStation (that represents this JACE) on the Supervisor. These values are written to the Supervisor upon any export tag Join.

Remember to save the bog file after any changes. Right-click the bog file and select Save. See Figure 28.

Note the profile.bog file is important for non-default properties of the “niagaraStation”, including also its “device extensions”, for example the Alarms extension and Users extension. For related details, see Device extension properties importance in profile.bog file.

You can also add new folders, point folders, and archive folders (containers) in the niagaraStation in this profile.bog file, saving it as you work. This allows you to select these items as the parent “Station Slot Path” property when adding various export tags. However, doing this is optional—alternatively, you can type a folder path directly in the “Station Slot Path” property of an export tag, or use special “BFormat” variables instead. For related information, see Station Slot Path considerations and BFormat options in Station Slot Paths.

Figure 29 shows the relationship of the JoinProfile’s “Station File” property and the resulting file folder and profile.bog file created, using property defaults.

The default ord of the Station File property in the JoinProfile is:

 file:^joinProfiles$(defaultStationFileName).bog

where the $(defaultStationFileName) portion is an ord variable that results in a .bog file named: SupervisorStationName_profile.bog

In the Figure 29 example, where the Supervisor station (and NiagaraStation that represents it) is named “Sup37_T1”, this results in a file named: Sup37_T1_profile.bog

If you edit the Station File property after the JoinProfile has already been enabled, you need to disable and then re-enable the JoinProfile for a new profile.bog file to be created—otherwise, Join errors may result. Be aware that this does not delete (or rename) the original profile.bog file.
