Api.CoeWriteSdoObject method

Writes the value of an SDO object through CANopen over EtherCAT (CoE). The module table is different for each module and can be obtained in the user manual of the module. This method takes multiple cycles to finish.

Syntax

C#VB

public KsCommandStatus CoeWriteSdoObject(
       int SlaveId,
       int ObIndex,
       int ObSubIndex,
       bool CompleteAccess,
       byte[] Value
)

Public Function CoeWriteSdoObject(
       SlaveId As Integer,
       ObIndex As Integer,
       ObSubIndex As Integer,
       CompleteAccess As Boolean,
       Value As Byte[]
) As KsCommandStatus

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.

ObIndex

Type: int

The CANopen index of the object. See your device manual to get the value.

ObSubIndex

Type: int

The CANopen subindex of the object. See your device manual to get the value.

CompleteAccess

Type: bool

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

Value

Type: byte[]

The buffer containing the data to be written to the object.

Return value

Type: KsCommandStatus

Returns the KsCommandStatus class.

Remarks

Used to update the drive configuration while the drive is disabled. You should read the drive's manual to learn when and how to use the SDO. If you call this method when the drive is enabled, an error may occur, depending on the response of your drive.

Usable EtherCAT states
