The Event totalization extension tracks the number of binary events or pulses over time, meaning it counts the number of transitions that occur at an input reference. Unlike other types of totalization, event totalization increases the value each time the event occurs, instead of calculating the value once each minute.

These three essential parameters determine the mode of operation for the Event totalization extension:

  • the monitored Input Reference
  • the types of recorded Transitions or events
  • the recorded Value Per Pulse (event)

You can use this extension to determine the number of changes in an input value, which may be helpful for maintaining and monitoring equipment. For example, use Event Totalization to determine how many times a motor started, how often a sensor was in alarm, or how many cars entered a parking lot.

The Event totalization extension contains attributes common to Metasys system objects. The following table lists the attributes specific to the Event totalization extension.
Note: The letters in the Notes column indicate the following: C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Extension’s Reliability, W - Writable.
