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.
IndexGroup
Type: int
The index group of the object to read and write.
IndexOffset
Type: int
The offset of the object in the group.
ReadLength
Type: int
The length in byte of the value to read.
WriteValue
Type: byte[]
The buffer containing the value to be written.
Return value
Type: KsCommandStatus<byte[]>
Returns a state of a method and a byte array.
Usable EtherCAT states
ecatPreOP, ecatSafeOP, ecatOP
