BYTE
Object subindex
dwTimeout
DWORD

• If the action could not be carried out successfully after time-out, bError is set
to TRUE.
• The time required for the action depends on the structure of the EtherCAT
network.
wSlaveStationAddress
WORD

• Designation in the EtherCAT configurator: "EtherCAT address"
• Designation in the EtherCAT specification and parameter reference: "Physical
address".
