The ComponentTag is an available “general purpose” export tag, to replicate the tagged (parent) component under the NiagaraStation component on the Supervisor. Component tags create a copy of the component from the source station. They do not create a proxy. For example, if you change properties on the component with the tag in the source station, those changes are not reflected in the copy of the component located in the Supervisor station. In general, it may be best for a component that has an “out” slot, but has either a “null” (or no) proxyExt, such as many found in the kitControl module. Usage on any “container” type component is generally not recommended.

A ComponentTag can also replicate a “custom” component, including a “Program” component. An example is included in the exportTags palette, in the Examples folder (“ExportTagProgram”). Note that starting in AX-3.7, the station user being used in the Join process (Fox connection to Supervisor) must have “super user” privileges for a ComponentTag on a Program object to function correctly.

Unlike PointTags, components made from ComponentTags are not Niagara proxy points. Therefore, you can specify them to be located anywhere under the NiagaraStation component (that models this station) in the Supervisor station.

See To add ComponentTags for a “quick start” procedure on working with these tags. The remainder of this section provides more details on this export tag type.
