Accumulator point
An accumulator point is a standard point type with a fixed data structure that represents total
values. For example, an accumulator point can represent the volume of water that has flowed
into a tank or through a turbine.
If you have the appropriate security level, you can change the point's properties.
Caution:
Changing point properties in Station will not update the Quick Builder project.
Honeywell recommends that, after updating the point in Station, you upload it into
Quick Builder to synchronize the project.
Faceplate
Shows critical information about the point, and provides a convenient means of controlling
the point. Many faceplates look like the front panels of the field devices they represent.
See the topic titled "Typical faceplates for the major point types" for more information.
