About point components

In any NiagaraAX station, all real-time data is normalized within the station database as points, a special group of components. Figure 12 shows several types of control points, as listed in the control module palette in Workbench.

Figure 12. Point types

Each type of point may be used for different purposes in Workbench. When you engineer a job you may want to name a point, as shown in Figure 13 (a NumericWritable point named CondSetpoint). Points may be named and renamed but they retain their initial point type characteristics and their characteristic icon color.

Points serve as a type of shell in NiagaraAX, to which you may add point extensions. These extensions allow you to select only those functions that you need and thereby limit your point properties to just those that are necessary for your current application.
