IBus ¶ GetBusInfo (Method) GetBusState (Method) GetQoS (Method)

CANopenManager_Diag.GetBusInfo (METH) ¶ METHOD GetBusInfo : DED.ERROR Returns information about the associated CANbus. Interpretation of DED.BUS_INFO is as follows: Component Interpretation eType DED.BUS_TYPE.CANOPEN idSystem Network ID idInstance Instance number in I/O configuration (starting by 0) InOut: Scope Name Type Comment Return GetBusInfo DED.ERROR DED.ERROR.NO_ERROR if no error occurred while getting information. Inout buiInfo DED.BUS_INFO bus information

CANopenManager_Diag.GetBusState (METH) ¶ METHOD GetBusState : DED.BUS_STATE Returns the bus state of the associated CANBus. Following table defines the mapping between CAA Device Diagnosis DED.BUS_STATE and CL2.BUSSTATE . CAA Device Diagnosis CANbus state DED.BUS_STATE.RUNNING CL2.BUSSTATE.ERR_FREE , CL2.BUSSTATE.ACTIVE , CL2.BUSSTATE.WARNING DED.BUS_STATE.ERROR no driver found, CL2.BUSSTATE.BUSOFF , CL2.BUSSTATE.PASSIVE DED.BUS_STATE.UNKNOWN CL2.BUSSTATE.UNKNOWN InOut: Scope Name Type Comment Return GetBusState DED.BUS_STATE current bus state. Output xDiagnosisInfoAvailable BOOL TRUE , if red exclamation mark in device tree eError DED.ERROR DED.ERROR.NO_ERROR if bus state was retrieved wihout error.

CANopenManager_Diag.GetQoS (METH) ¶ METHOD GetQoS : DED.ERROR QualityInfo contains following information: usiBusload: Current Busload (if supported by CAN driver, else always 0) ctError: Total Sum of TxErrorCounter, RxErrorCounter and LostCounter. Returns quality of service information for the CANbus. Interpretation of DED.QOS_INFO is as follows: Component Interpretation ctError Total sum of TxErrorCounter, RxErrorCounter and LostCounter. usiBusload Current busload in percent (if supported by CAN driver, else always 0) InOut: Scope Name Type Comment Return GetQoS DED.ERROR DED.ERROR.NO_ERROR if no error occurred while getting information. Inout QualityInfo DED.QOS_INFO

IDevice ¶ CheckCurrentSupportedCommunicationState (Method) CheckSupportedCommunicationState (Method) GetDeviceInfo (Method) GetDeviceState (Method) SetCommunicationState (Method)

CANopenManager_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 CANopenManager_Diag.SetCommunicationState . Note Use CANopenManager_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.

CANopenManager_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 CANopenManager_Diag.SetCommunicationState . Note Use CANopenManager_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.

CANopenManager_Diag.GetDeviceInfo (METH) ¶ METHOD GetDeviceInfo : DED.ERROR Returns device information about the CANopenManager. Interpretation of DED.DEVICE_INFO is as follows: Component Interpretation eType DED.DEVICE_TYPE.FIELDBUS_MASTER idSystem Node ID idInstance Instance number in I/O configuration (starting by 0) InOut: Scope Name Type Comment Return GetDeviceInfo DED.ERROR DED.ERROR.NO_ERROR if no error occurred while getting information. Inout deiInfo DED.DEVICE_INFO device information

CANopenManager_Diag.GetDeviceState (METH) ¶ METHOD GetDeviceState : DED.DEVICE_STATE Returns the state of the CANopenManager. Following table defines the mapping between CAA Device Diagnosis DED.DEVICE_STATE and DEVICE_STATE . CAA Device Diagnosis CANopen state DED.DEVICE_STATE.UNKNOWN - DED.DEVICE_STATE.STOPPED DEVICE_STATE.STOPPED DED.DEVICE_STATE.RUNNING DEVICE_STATE.OPERATIONAL DED.DEVICE_STATE.ERROR bus error pending DED.DEVICE_STATE.DISABLED Device is disabled in I/O configuration. DED.DEVICE_STATE.NOT_CONFIGURED DEVICE_STATE.INIT DED.DEVICE_STATE.CONFIGURED DEVICE_STATE.PRE_OPERATIONAL DED.DEVICE_STATE.NOT_FOUND - InOut: Scope Name Type Comment Return GetDeviceState DED.DEVICE_STATE current device state Output xDiagnosisInfoAvailable BOOL TRUE , if red exclamation mark in device tree eError DED.ERROR
