CANopenDevice_Diag.GetDeviceInfo (METH) ¶ METHOD GetDeviceInfo : DED.ERROR Returns device information about the CANopen slave. Interpretation of DED.DEVICE_INFO is as follows: Component Interpretation eType DED.DEVICE_TYPE.FIELDBUS_SLAVE 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 struct

CANopenDevice_Diag.GetDeviceState (METH) ¶ METHOD GetDeviceState : DED.DEVICE_STATE Returns the state of the CANopen slave. Following table defines the mapping between CAA Device Diagnosis DED.DEVICE_STATE and CANOPEN_STATE . CAA Device Diagnosis CANopen state DED.DEVICE_STATE.UNKNOWN - DED.DEVICE_STATE.STOPPED CANOPEN_STATE.STOPPED DED.DEVICE_STATE.RUNNING CANOPEN_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 CANOPEN_STATE.INIT DED.DEVICE_STATE.CONFIGURED CANOPEN_STATE.PREOPERATIONAL 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

CANopenDevice_Diag.SetCommunicationState (METH) ¶ METHOD SetCommunicationState : DED.ERROR Starts, stops or resets the device. Following table defines the mapping between CAA Device Diagnosis DED.DEVICE_TRANSITION_STATE and CANopen NMT command: CAA Device Diagnosis CANopen NMT command DED.DEVICE_TRANSITION_STATE.START NMT Start ( CANopenDevice.SwitchToOp ) DED.DEVICE_TRANSITION_STATE.STOP NMT Stop ( CANopenDevice.SwitchToStopped ) DED.DEVICE_TRANSITION_STATE.RESET If current state is CANOPEN_STATE.POWERDOWN : CANopenDevice.PowerUp else NMT Reset ( CANopenDevice.Reset ) Note Use CANopenDevice_Diag.CheckCurrentSupportedCommunicationState to check which transitions are possible in the current state! InOut: Scope Name Type Comment Return SetCommunicationState DED.ERROR DED.ERROR.NO_ERROR if device transition was successful. Input eRequestedState DED.DEVICE_TRANSITION_STATE desired transition

INode ¶ Methods for traversing the device tree. ChildNodeCount (Property) Connector (Property) Enable (Property) FirstChildNode (Property) Index (Property) IsRootNode (Property) NextSiblingNode (Property) ParentNode (Property) SiblingNodeCount (Property)

CANopenDevice_Diag.ChildNodeCount (PROP) ¶ PROPERTY ChildNodeCount : CAA.COUNT Returns the number of childs below the current node

CANopenDevice_Diag.Connector (PROP) ¶ PROPERTY Connector : POINTER TO IoStandard.IoConfigConnector

CANopenDevice_Diag.Enable (PROP) ¶ PROPERTY Enable : BOOL Set: This property is used for enabling/disabling a node. Note Changes will take effect after reconfiguring (see DED.Reconfigure ). Get: Returns the current value

CANopenDevice_Diag.FirstChildNode (PROP) ¶ PROPERTY FirstChildNode : DED.INode Returns the first child node below the current one

CANopenDevice_Diag.Index (PROP) ¶ PROPERTY Index : UDINT

CANopenDevice_Diag.IsRootNode (PROP) ¶ PROPERTY IsRootNode : BOOL returns TRUE , if the current node is the root (plc) node, otherwise FALSE
