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.
