8.2.9.1 StateChangedEventType ToC

StateChangedEventType is an EventType subtype of TransitionEventType, defined in OPC 10000-5. This event shall be triggered by the server whenever the system enters a new state.It is formally defined in Table 93. The event transports the NodeId of the state entered as well as the transition which is leading into that state.

Refer to the TransitionEventType in OPC 10000-5 for the behavior and the transported information.

8.2.9.2 ErrorEventType ToC

ErrorEventType is an EventType subtype of TransitionEventType, defined in OPC 10000-5. This event must be triggered when the vision system decides that the current conditions require it to suspend normal operation and enter state Error. Additional detail about the circumstances leading to the Error state shall be indicated by active ConditionType events. For more detail see Section 11.

8.2.9.3 ErrorResolvedEventType ToC

ErrorResolvedEventType is an EventType subtype of TransitionEventType, defined in OPC 10000-5. This event must be triggered when the vision system decides that the current conditions do not require state Error to be maintained and initiates the transition into whatever state it deemed appropriate under the circumstances.

It is formally defined in Table 95.
