D.20 RIO
LAN A
Switch B is also configured to support a VLAN on a certain network port, which is
connected to the D.20 RIO. Since this port is dedicated to the VLAN, only information
flagged for the VLAN is transmitted to the D.20 RIO. As well, information sent on this VLAN
from the D.20 RIO device can be classified with a higher priority, which will ensure a higher
likelihood of transmission during times of network congestion.
You can configure the following options on each VLAN you create:
•
IP address, subnet mast, and default gateway: You can assign static values or obtain
dynamic values via DHCP. Once you have configured these values, you can use them
to access your VLAN.
•
EGRESS priority mappings: Set the QoS priority level for data transmitted on this VLAN.
Priority levels range from 0 to 7 with 7 being the highest priority. If a QoS-enabled
device receives packets transmitted on this VLAN, it should apply prioritization based
on the level you specify.
•
Ethernet reorder flag header: This option is reserved for use by GE Digital Energy staff
for customer support tasks.
When the D.20 RIO is configured for VLAN, manually set the D.20 RIO's VLAN IP address.
From the D.20 RIO HMI, select: Connections > D.20 Client > Configuration Parameters >
IP Address field.
Before enabling or disabling LAN Redundancy (i.e., for a bonded network) you need to
remove the VLAN ID's created in the network interfaces of the D.20 RIO.
To disable LAN redundancy if a VLAN is configured:
1.
Connect to the rear maintenance RS-232 port. See "D.20 RIO field and network
connectors" on page 29.
2.
At the D20RIO#>> prompt, type d20riocfg and press Enter.
Result: The D20RIO Configuration Utility menu appears.
3.
Type 3 and press Enter to select 3. Configure Network Interfaces.
Result: The Network Interface menu appears.
4.
Type 1 and press Enter to select 1.Configure Bond0.
Result: The Bond0 menu appears.
5.
Type 4 and press Enter to select 4. VLAN.
