DLRallows devices to be placed in a ring to reduce the need for switch hardware and cabling and allow for the detection andrecovery of faults in the ring. This option is a beacon based ring node implementation.To set up a DLR network, configure a supervisor on the network prior to connecting and powering on all devices in the ring.Establishing a ring without an active supervisor may cause a loss of communication to devices on the ring.The supervisor precedence must be configured when setting up the supervisor. Typically, the default beacon rate is 400 ms toallow for faster fault detection and recovery period and should be fast enough for devices to recover on the ring without losingan I/O connection. The precedence value for the supervisor is used when more than one supervisor is present. When twosupervisors are on the network, the supervisor with the higher MAC address will become the supervisor and the other willbecome a backup supervisor.Yaskawa recommends that all devices in the ring be DLR capable. Add non-DLR devices to the ring through a DLR-capabledevice, such as a 3-port ETAP.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 undesiredbehavior 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, ifa 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 cabledisconnected. Make the last connection after configuring the nodes and supervisor.Note: DLR is supported in option software versions VST800341 and later.n Services SupportedService Code No. (Hex) Service Name01 Get Attribute All10 Set Attribute Singlen Attributes SupportedInstanceID Attribute Name Description Get Set Size Range Default0 1 Object SoftwareRevision Revision number of the DLR Object O – Word – 31 1 NetworkTopologyCurrent network topology mode0: Linear1: Ring O – Byte 0, 1 01 2 Network StatusCurrent status of network0: Normal1: Ring fault2: Unexpected loop detected3: Partial network fault4: Rapid fault/restore cycleO – Byte 0 to 4 –11 General Class ObjectsYASKAWA SIEPYAICOM22 Rev: A0 Bypass Option Single and Dual-Port EtherNet/IP SI-EN3/SI-EN3D Technical Manual 53 |
