Instrument Control Toolbox

TimerFcn

Specify the M-file callback function to execute when a predefined period of time passes

Description

You configure TimerFcn to execute an M-file callback function when a timer event occurs. A timer event occurs when the time specified by the TimerPeriod property passes. Time is measured relative to when the object is connected to the instrument with fopen.

Note    A timer event can be generated at any time during the instrument control session.

If the RecordStatus property value is on, and a timer event occurs, the record file records this information:

• The event type as Timer
• The time the event occurred using the format day-month-year hour:minute:second:millisecond

Some timer events might not be processed if your system is significantly slowed or if the TimerPeriod value is too small.

To learn how to create a callback function, refer to Creating and Executing Callback Functions.
