This object holds the most recent data payload that was sent along with a generic user-defined event on this WISI Tangram device, effectively acting as a scratch value carrying whatever information accompanied the last such event. Administrators or integration scripts write to this object to trigger a custom notification carrying arbitrary data, then the device's trap mechanism reports that data to a management station. For example, an integrator might set this to a custom status code before triggering a user event, so that value is captured and forwarded in the resulting trap.
