Yaskawa V1000 Option Dual Port EtherNet/IP SI-EN3D/V Technical Manual - Manual (Page 48)

Ensure that non-DLR devices placed in the ring meet the following requirements:
• Disable MAC address learning
• Do not use multicast filtering
• Preserve VLAN tags.
Make sure that all switches in the ring are DLR-aware. Switches in the ring that are not DLR-aware may cause undesired
behavior due to MAC address learning of the supervisor beacon packets being received on two different switch ports.
Be sure to set the RPI only as fast as needed to limit the network traffic. Yaskawa supports RPIs down to 10 ms. However, if
a slower level of control is acceptable, a slower RPI setting will reduce network traffic.
Yaskawa also recommends setting up and configuring all devices prior to completing the ring by leaving one cable
disconnected. Make the last connection after configuring the nodes and supervisor.
Note: DLR is supported in option software versions VST800341 and later.
