SPCAlarms

Returns the status of the specified SPC alarm. This function is used to configure SPC alarms, by defining alarms with this trigger in Advanced Alarms.

This function can only be used if the Alarm Server is on the current machine. When the Alarm Server is not in the calling process, this function will become blocking and cannot be called from a foreground task. In this case, the return value will be undefined and a Cicode hardware alarm will be raised.
