IsAutomated being True indicates that the interruption will automatically end in normal operation of the machine tool. A tool change for example can be automated and handled by the machine tool itself. The tool change might also not be automated. In that case an operator has to change the tool manually.

To indicate the reason for the process to be interrupted, the Components ConditionClassId and ConditionClassName of the InterruptionConditionType shall indicate the most appropriate ConditionClass. This specification defines special ConditionClasses relevant to the domain of machine tools (see 10). Of the ConditionClasses defined in OPC 10000-9, especially the SafetyConditionClassType shall be considered as well.
