*1. The IO-Link Master Unit conforms to the EtherCAT standards. Confirm the specifications of the connected EtherCAT
master for the supported topology. Note that the IO-Link Master Unit supports the ring topology.
*2. For the ring topology, the minimum value of the supported communications cycle is 125 µs. Allowing the IO-Link Mas-
ter Unit to operate with a shorter communications cycle than the minimum value may cause the loss of EtherCAT com-
munications frames or a communications stop.
*3. The setting range of the node address depends on the specifications of the connected EtherCAT master. Check the
specifications of the EtherCAT master for the supported node address setting range of the EtherCAT master.
