The Analog totalization extension tracks and records the usage of any consumable monitored through an analog attribute. Some examples of consumables include electricity, gas, steam, and chilled water.

These three essential parameters determine the Analog totalization extension’s mode of operation:

  • the Input Reference to be monitored
  • the Timebase on which the computation is based
  • the Low CutOff Value that the input must meet or exceed

Use the Analog totalization extension to determine the usage of the given consumable. For example, you can determine the amount of gas or steam used by the facility for a given month. Also, use Analog totalization to determine how many kilowatt/hours were used in a week or to totalize a calculated value (for example, degree days).

The Analog totalization extension contains attributes common to Metasys system objects. The following table lists the attributes specific to the Analog totalization extension.

Note: In the Notes column, the letters indicate the following: C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Extension’s Reliability, W - Writable.
