Point Tags are used to export selected components to the Supervisor station as Niagara proxy points. They are similar to ComponentTags, but include additional properties for Conversion type and (NiagaraNetwork) Tuning Policy Name. In general, use a PointTag for any source proxy point in the JACE station, that is any component that has a working (non-null) ProxyExt of any type. For more details, see PointTags.
