EtherCAT Communications Specifications

*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 Master Unit to operate with a

shorter communications cycle than the minimum value may cause the loss of EtherCAT communications 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.
