ModbusTCPSlaveUnit_Diag.GetSpecificDeviceErrorAsync (METH) ¶ METHOD GetSpecificDeviceErrorAsync : DED.PROC_STATE Returns the specific device error of the current node; interpretation is fieldbus-dependent; you can also use functionblock GetSpecificDeviceError InOut: Scope Name Type Comment Return GetSpecificDeviceErrorAsync DED.PROC_STATE Input eCmd DED.PROC_CMD eCommand pData CAA.PVOID Pointer to memory szSize CAA.SIZE Size of memory in bytes where pData is pointing to Output szCount CAA.SIZE Number of Bytes written to pData eError DED.ERROR error code if method fails
ModbusTCPSlaveUnit_Diag.GetSpecificDeviceState (METH) ¶ METHOD GetSpecificDeviceState : DED.ERROR Returns the fieldbus specific device state; interpretation is fieldbus dependent InOut: Scope Name Type Comment Return GetSpecificDeviceState DED.ERROR Input pData CAA.PVOID Pointer to memory szSize CAA.SIZE Size of memory in bytes where pData is pointing to Output szCount CAA.SIZE Number of Bytes written to pData
ModbusTCPSlaveUnit_Diag.SetCommunicationState (METH) ¶ METHOD SetCommunicationState : DED.ERROR Starts, stops or resets a device InOut: Scope Name Type Return SetCommunicationState DED.ERROR Input eRequestedState DED.DEVICE_TRANSITION_STATE
INode ¶ ChildNodeCount (Property) Enable (Property) FirstChildNode (Property) IsRootNode (Property) NextSiblingNode (Property) ParentNode (Property) SiblingNodeCount (Property)
ModbusTCPSlaveUnit_Diag.ChildNodeCount (PROP) ¶ PROPERTY ChildNodeCount : CAA.Count
ModbusTCPSlaveUnit_Diag.Enable (PROP) ¶ PROPERTY Enable : BOOL This property returns if the node is enabled in the device tree. The setter can be used to change the Enabled flag. If enabling/disabling is not supported on the node the flag’s value will not change.
