Data Acquisition Toolbox

Configuring Events and Actions

You can enhance the power and flexibility of your analog input application by utilizing events. An event occurs at a particular time after a condition is met and may result in one or more actions.

While the analog input object is running, you can use events to display a message, display data, analyze data, or perform just about any other action. Actions are controlled through action properties and action functions. All event types have an associated action property. Action functions are M-file functions that you construct to suit your specific data acquisition needs.

You execute an action when a particular event occurs by specifying the name of the M-file action function as the value for the associated action property. Note that daqaction is the default value for some action properties.
