This is used for products which do not have Ethernet redundancy and applies only to those using single
Ethernet boards. This board has one fibre and one copper interface. If there is a fault on the fibre channel it
can switch to the copper channel, or vice versa. Px4x products which use the Parallel Redundancy Protocol(PRP) do not need this function.
When this function detects a link failure, it generates the NIC Fail Alarm. The failover timer then starts, which
has a settable timeout of 2 to 60 secs in 100 ms steps. During this time, the Hot Standby Failover function
continues to check the status of the other channel. If the link failure recovers before the failover timer times
out, the channels are not swapped over. If there is still a fail when the failover timer times out and the other
channel status is ok, the channels are swapped over. The Ethernet controller is then reconfigured and the
link is renegotiated.
4.1 HOT-STANDBY ETHERNET FAILOVER SETTINGS
To set the function:
1. Start S1 Agile.
2. Click the Ethernet Configuration tile.
3. Start the IEC 61850 IED Configurator.
Working offline:
1. Click the icon New MiCOM Configuration from an Installed ICD File.
2. Double-click the product variant.
3. Double-click the Communications item.
Or working online:
1. Select Device > Manage IED.
2. Select the IED type device number.
3. Select the IED address and click Next. The IED 61850 Configurator tool reads information from the
IED and shows them in the Summary view.
4. Click the Communications tab to read and edit the settings.
Then:
1. The Media setting defines the default interface used to communicate between clients and peers, and
the MiCOM IED. The value is taken from the ConnectedAP/PhysConn section of the configured SCL
file and is editable in Manual Editing Mode. The single Ethernet board has one fibre and one copper
interface. If you are using fibre, select Single Fibre. If you are using copper, select Single Copper or
Redundant Fibre. If you are using a Redundant Ethernet board, select Single Copper or Redundant
Fibre.
2. Set the Ethernet Failover to Enable and adjust the Failover Timeout as required. This does notappear if the product does not have Ethernet Failover.
