CANopenDevice_Diag.CheckCurrentSupportedCommunicationState (METH) ¶ METHOD CheckCurrentSupportedCommunicationState : BOOL This method checks if a specific DED.DEVICE_TRANSITION_STATE can be processed in the current state. For more details on interpretation of DED.DEVICE_TRANSITION_STATE for CANopen see CANopenDevice_Diag.SetCommunicationState . Note Use CANopenDevice_Diag.CheckSupportedCommunicationState to check which DED.DEVICE_TRANSITION_STATE is supported in general. InOut: Scope Name Type Comment Return CheckCurrentSupportedCommunicationState BOOL TRUE if node supports the requested DED.DEVICE_TRANSITION_STATE in the current state. Input eRequestedState DED.DEVICE_TRANSITION_STATE The communication state to be checked.

CANopenDevice_Diag.CheckSupportedCommunicationState (METH) ¶ METHOD CheckSupportedCommunicationState : BOOL This method checks if a specific DED.DEVICE_TRANSITION_STATE is supported by the node in general. For more details on interpretation of DED.DEVICE_TRANSITION_STATE for CANopen see CANopenDevice_Diag.SetCommunicationState . Note Use CANopenDevice_Diag.CheckCurrentSupportedCommunicationState to check which DED.DEVICE_TRANSITION_STATE is possible in the current state. InOut: Scope Name Type Comment Return CheckSupportedCommunicationState BOOL TRUE if node supports the requested DED.DEVICE_TRANSITION_STATE in general. Input eRequestedState DED.DEVICE_TRANSITION_STATE The communication state to be checked.

IODCallback (ITF) ¶ INTERFACE IODCallback EXTENDS __SYSTEM.IQueryInterface This interface must be implemented if someone wants to register an ObjectDictionary callback for read and write operations via the IObjectDictionary.RegisterCallback method of IObjectDictionary . All write and read operations on objects can be monitored and aborted by returning an appropriate abort code.
