Assembly: IntervalZero.KINGSTAR.OpcUa.Api (in IntervalZero.KINGSTAR.OpcUa.Client.dll) Version: 4.4.0.0

Syntax

C#VB
public KsCommandStatus<byte[]> AoeReadSdoObject(
       int SlaveId,
       int Port,
       int ObIndex,
       int ObSubIndex,
       bool CompleteAccess,
       int Length
)
Public Function AoeReadSdoObject(
       SlaveId As Integer,
       Port As Integer,
       ObIndex As Integer,
       ObSubIndex As Integer,
       CompleteAccess As Boolean,
       Length As Integer
) As KsCommandStatus(Of Byte[])

Parameters

SlaveId

Type: int

The slave index. This index value is automatically assigned by the KINGSTAR master when the EtherCAT network starts, based on the physical connection order. The first device connected directly to the master is assigned Index 0, followed by Index 1, Index 2, and so on. These indexes remain consistent within the slave array even if devices are added, removed, or reconnected. Please refer to the use cases in HotConnect, Repair, and Restart for more details.

 

Port

Type: int

The EtherCAT slave port.

 

ObIndex

Type: int

The index of the object to read in the object dictionary.

 

ObSubIndex

Type: int

The subindex of the object to read in the object dictionary.

 

CompleteAccess

Type: bool

TRUE: Reads all subindexes. FALSE: Reads a single subindex.

 

Length

Type: int

The length in byte of the value to read.

Return value

Type: KsCommandStatus<byte[]>

Returns a state of a method and a byte array.

Usable EtherCAT states

ecatPreOP, ecatSafeOP, ecatOP
