Sigmafine TimeInState Data Reference Introduction

The Sigmafine TimeInState Data Reference is used to provide information pertaining to how much time a PI tag has been in a certain state, or in other words, it can calculate the Run Time. This data reference is only valid in the context of a case.

EXAMPLE: Sigmafine TimeInState Data Reference

	PI Tag State is in ®	‘On’ state for 10 hours‘Off’ state for 4 hoursAnd then ‘On’ state for another 10 hours.
	Results ®	20 hours for ‘On’ state and 4 hours for ‘Off’ state.

The result of a TimeInState calculation is displayed in either time UOM or in %. The PI Point Data Reference does not have the capability to calculate the Run Time, making TimeInState Data Reference useful in performing that calculation.

Note: ‘On’ and ‘Off’ states are mentioned for explanation purposes only. It is not required for a PI Tag to be a Digital State PI Tag. The Data Reference will function for any PI Tag with any value.

Required Data Reference Attribute

The Sigmafine TimeInState Data Reference requires that an Attribute be added to an Element so that the data reference can be configured. The Element can be based on any existing template or you can create a new template. Requirements for the Element Attribute are described in the \remaining topics under Sigmafine TimeInState.

This data reference also requires that elements have an Attribute with the Value Type of “Anything”. The Attribute name can be anything you choose.

Element Attribute

Name of Attribute Being Configured	Attribute Unit of Measure	Template Name	Parameter Value Type
Can be any name	\<None>	Can be any existing template or a new template and name; it does not matter	Anything
