Key parameters for PI totalizer tags

PI totalizer tags are essential for accurately summarizing and analyzing data over specified periods. Understanding these parameters will help you set up and optimize your totalizer tags for precise data accumulation and reporting.

Totalizer tag configuration

Configure the following parameters to define how the totalizer gathers and processes data:

• SourceTag: The tag from which the totalizer will gather data.

• Calculation basis: Specifies whether the totalizer should use event-weighted or time-weighted calculations.

• Time interval: Defines the period over which the data will be accumulated.

• OutputTag: The tag where the totalized value will be stored.

Sampling and reporting

Set these parameters to control the frequency of data sampling and reporting:

• Sample interval: The frequency at which the source tag is sampled.

• Report Interval: How often the totalizer writes the totalized value to the output tag.

Optional configurations

Use these optional settings to refine the totalizer's behavior:

• Reset condition: Conditions under which the totalizer should reset its calculations.

• Deadband: The minimum change in value that triggers a new totalizer calculation.

• Filter expression: A condition that must be met for the totalizer to include a value in its calculation.
