IBus ¶ Functions for getting bus information. GetBusInfo (Method) GetBusState (Method) GetQoS (Method)

CANopenDevice_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 struct

CANopenDevice_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.

CANopenDevice_Diag.GetQoS (METH) ¶ METHOD GetQoS : DED.ERROR 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
