Starting in AX-3.4, Baja virtual components were implemented in the niagaraDriver. This allowed a Supervisor station access to Niagara virtual components (or simply “Niagara virtuals”), via a “Virtual gateway” under each NiagaraStation in its NiagaraNetwork. These dynamically-created Niagara virtual components provided monitor access to the entire component structure of each remote JACE station—without the overhead (or engineering necessity) of Niagara proxy points.

In AX-3.5, enhancements were made to Niagara virtuals. Most notable was that Niagara virtuals now provided write access to most properties. In addition, point status was improved for virtuals of control points (typical usage in proxy points among various driver types).
