Namespace: IntervalZero.KINGSTAR.OpcUa.Api
Assembly: IntervalZero.KINGSTAR.OpcUa.Api (in IntervalZero.KINGSTAR.OpcUa.Client.dll) Version: 4.4.0.0
Syntax
public KsReturn<SlaveStatus> GetSlaveById(
int Index
)
Public Function GetSlaveById(
Index As Integer
) As KsReturn(Of SlaveStatus)
Parameters
Index
Type: int
The index of a slave array. When EtherCAT is started, this index has the same value as the SlaveId, which corresponds to the position of the slave in the network. Please note that after EtherCAT is started in the Operational (Op) state, any addition or removal of slaves from the network will change the position of the slaves in the network (SlaveId). Nevertheless, the index of the slave will remain the same. Newly added devices will be added in the back of the slave array. For all slaves after the change, the index and SlaveId will no longer match. This behavior is only available for physical devices; simulated devices are inapplicable. Please refer to the use cases in EnableHotConnect for more details.
Return value
Type: KsReturn<SlaveStatus>
Returns a KsError code and a SlaveStatus value.
Remarks
Retrieves details about a specified slave using the slave’s position in the EtherCAT loop. Since it uses the slave ID, it doesn't use the alias information. It works only for real slave modules without separating axes or I/Os. Use after the KINGSTAR Subsystem starts.
Usable EtherCAT states
ecatInit, ecatBoot, ecatPreOP, ecatSafeOP, ecatOP
