Data Acquisition Toolbox

start

Start a device object

Syntax

start(obj)

Arguments

obj	A device object or an array of device objects.

Description

start(obj) initiates the execution of the device object obj.

Remarks

When start is issued for an analog input or analog output object:

• The M-file action function specified for StartAction is executed.
• The Running property is set to On.
• The start event is recorded in the EventLog property.
• Data existing in the engine is flushed.

Although an analog input or analog output object may be executing, data logging or sending is not necessarily initiated. Data logging or sending requires a trigger event to occur, and depends on the TriggerType property value.

For any device object, you can specify start as the value for an action property.

ai.StopAction = 'start';

Note    You typically execute a digital I/O object to periodically update and display its state. Refer to the diopanel demo for an example of this.
