Sercos3Slave_Diag.ParentNode (PROP) ¶ PROPERTY ParentNode : INode Returns the parent node or zero if the root node is already reached.
Sercos3Slave_Diag.SiblingNodeCount (PROP) ¶ PROPERTY SiblingNodeCount : CAA.Count Returns the number of sibling (same level) nodes
Sercos3Slave_Diag.SetCommunicationState (METH) ¶ METHOD SetCommunicationState : DED.ERROR Starts, stops or resets a device Note Use |IDevice2.CheckSupportedCommunicationState| and |IDevice2.CheckCurrentSupportedCommunicationState| to check which transitions are possible! InOut: Scope Name Type Comment Return SetCommunicationState DED.ERROR Input eRequestedState DED.DEVICE_TRANSITION_STATE desired transition

ENUMS ¶ SERCOS3_ERROR (Enum)
Sercos3Slave_Diag.ChildNodeCount (PROP) ¶ PROPERTY ChildNodeCount : CAA.Count Returns the number of childs below the current node
Sercos3Slave_Diag.Enable (PROP) ¶ PROPERTY Enable : BOOL Set: This property is used for enabling/disabling a node. Changes will take effect after doing a Reconfigure (see |Reconfigure| ). Get: Returns the current Enable value

ClientRequest Output eErrorID Error Error status ClientRequest eException ExceptionCodes Request exception code. ClientRequest uiRetryCnt UINT 0 Number of request retries in case of “reply timeout”. ClientRequest Input uiStartItem UINT 0 First “data item” to read. ClientRequestRead uiQuantity UINT 1 Number of “data items” to read.

The ClientRequest has to know about the “data item” size a-priori to provide memory for result data. In case the server unexpectedly does have a different “data item” size than assumed, the ClientRequest can not succeed.
ClientRequestReadWriteMultipleRegistersWide (FB) ¶ FUNCTION_BLOCK ClientRequestReadWriteMultipleRegistersWide EXTENDS ModbusFB.ClientRequest ReadWriteMultipleRegister client request (FC23) for registers > 16bit. For details about client request see |ClientRequest| . For details about “wide registers” and endianess see ServerTCP_extended or ServerSerial_extended .
