Operator that translates an event with captured values into a sample with those values at its output, or those values in an editable list.

Event Information

Overview

Use the Event Information operator to view and manipulate captured values in events.

Operator ports

Input Any: Any sample type. The connection is not limited to one type of signal.

Output Event values: Floating point values

Properties

Find more information about changing properties here: "Properties Viewer"

EventCode

type: See description
Name of the event marker that this operator makes available for information to the project.

SyncID

type: See description
Synchronization code to synchronize the data cursor with other viewers

Caption

type: Word or phrase
The name of the object in the project. This name must not contain '.', '$' nor '@' characters.

For more information about the rules and usage of the Caption property, please refer to "Caption property - background and usage".

Documentation

type: See description
Optional documentation of this object. If this object is an operator, the Documentation text is displayed below the operator symbol.

Variable Parameters

Find more information about Variable Parameters here: "Variable Parameters"

TimeStamp

type: See description [this value cannot be changed]
The time stamp of the event marker that is currently shown, expressed as a time value.

TimeStampSeconds

type: See description [this value cannot be changed]
The time stamp of the event marker that is currently shown, expressed in seconds.

Values

type: Parameter list (see "Parameter List")
All the values in the event marker that is currently shown.

SequenceNumber

type: See description
Sequence number of the current event in the row of events with the specified code that have occurred in the past (starting with 0).

Details

Which event is the current event in the Event Information operator, depends on its input connection.

If the operator is connected to a live data stream, then the last event in that stream that has the Event Code as set in the properties is the current event.

If the operator is connected to a Storage or Replay operator, in a way that stored data are accessible (so only Preparation operators may be in between), then there are two options to control which event is read from the data store:

1) by using the Data Cursor. You then have to specify a SyncID, which should be the same as one in an object that can change the Data Cursor. For example a Y-T Reviewer, or an Event Viewer, both that need to have an equal SyncID.
2) by using the SequenceNumber variable parameter. This refers to the sequence of events. You must leave the SyncID property empty if you want to use the sequence numbers!

Examples

Example: Event Information Demo

Demonstrates how the Event Information is used to find specific event markers in a signal file, and display some details about the event marker. In this demo, the Event Information operator works in the Sequence Number mode, so which event is displayed depends on the sequence number variable.
The Marker Viewer in this example does nothing; it is there just to show all events for your information.
If events contain one or more values, the values are displayed in the List Viewer to the right.
