CANbus (FB) ¶ FUNCTION_BLOCK CANbus Note Do not instantiate this function block! An implicit instance will be created for each CANbus in the device tree. Properties: AutoRecovery Baudrate BusAlarm BusState NetId Methods: ResetBusAlarm Structure: AutoRecovery (Property) Baudrate (Property) BusAlarm (Property) BusState (Property) NetId (Property) ResetBusAlarm (Method)

CANbus.AutoRecovery (PROP) ¶ PROPERTY AutoRecovery : BOOL If AutoRecovery is enabled CANbus.ResetBusAlarm is automatically called when CANbus.BusAlarm is TRUE . If AutoRecovery is disabled CANbus.ResetBusAlarm has to be called by application. Default value: TRUE

CANbus.Baudrate (PROP) ¶ PROPERTY FINAL Baudrate : UINT Returns the currently used Baudrate. Baudrate can be changed with CANbus_Diag.SetBaudrate if device diagnosis is activated (needs Reconfigure !).

CANbus.BusAlarm (PROP) ¶ PROPERTY BusAlarm : BOOL Returns TRUE if CAN driver signals a BusAlarm (e.g. Bus Off). Call CANbus.ResetBusAlarm to reset the alarm or enable CANbus.AutoRecovery .

CANbus.BusState (PROP) ¶ PROPERTY BusState : CL2.BUSSTATE Returns the current CANbus state. Only valid if at least one enabled CAN based stack is attached to this CANbus.

CANbus.NetId (PROP) ¶ PROPERTY FINAL NetId : USINT Returns the currently used Network ID. Network ID can be changed with CANbus_Diag.SetNetId if device diagnosis is activated (needs Reconfigure !).

CANbus.ResetBusAlarm (METH) ¶ METHOD ResetBusAlarm : BOOL Resets a bus alarm and returns TRUE in case of success. Note: Method is only working if there is at least one active CAN based stack below this CANbus. Resetting bus alarm will be done asynchronously in the attached CAN based stack. InOut: Scope Name Type Return ResetBusAlarm BOOL

CANbus_Diag (FB) ¶ FUNCTION_BLOCK CANbus_Diag EXTENDS CANbus IMPLEMENTS DED.IBus, DED.IReconfigureProvider Note Do not instantiate this function block!
