A SCADA Point is a core component of a SCADA monitoring system

A SCADA (Supervisory Control and Data Acquisition) point is a data element within a distributed database in a SCADA system. A distributed, or tag, database contains points which refer to singular input or output values that are monitored by the SCADA system. SCADA systems equipped with control relays can also control these input and output value points.

SCADA Points Classified as "Hard" or "Soft"
These points fall into two categories. A SCADA point can be classified as a "hard" point or a "soft" point. While hard points represent actual inputs or outputs connected to the SCADA system, a SCADA point that is classified as a soft point represents results from math and logic operations other hard and soft points in the system.

A system will normally store SCADA point values as a combination of the value and timestamp that correlates to when the value was recorded. When looking at a history of these SCADA point values, network operators can view a history of that individual point.

SCADA Point Histories Can Pinpoint Problems With Individual Network Devices
Looking at a SCADA point history can be beneficial to operators when monitoring their network in great detail. These SCADA point histories can alert operators when they may be experiences a recurring problem with a specific input or output device, enabling them to make the necessary changes to keep their network functioning at maximum efficiency.
