The Runtime totalization extension tracks the time that elapses while a designated input, such as a binary or multistate value, matches a specified state.

These two essential parameters determine the Runtime totalization extension’s mode of operation:

  • the monitored Input Reference
  • the Reference (state) that identifies active runtime

Use this extension to track the amount of time that a piece of equipment, such as a fan or a pump, is operational. This extension also determines the amount of time that a point is in alarm or the runtime of fixed loads (such as lighting) for energy consumption and tenant billing.

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