The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, HTTP, and PRP protocols. PRP is
explained in its own section later.
Use the front panel to change these settings. When online, the EnerVista software can be used to enable/disable each port
only. In the Offline Window area, all settings can be changed except port 2 redundancy (depending on firmware version).
When using GOOSE, in failover or PRP mode, port 3 configuration in the CID file is ignored. The Port 3 ConnectedAP
elements has no meaning, as ports 2 and 3 use the port 2 MAC address, IP address, and mask.
PRT1 (2 or 3) IP ADDRESS — This setting sets the port’s IPv4 address in standard IPV4 format. This setting is valid on port 3 if
port 2 REDUNDANCY is set to None.
PRT1 (2 or 3) SUBNET MASK — This setting sets the port’s IPv4 subnet mask in standard IPV4 format. This setting is valid on
port 3 if port 2 REDUNDANCY is set to None.
PRT1 (2 or 3) FUNCTION — This setting enable/disables network communication on the respective port. When the port
function is Disabled, the network traffic on this port is disabled. The PRT2 redundancy setting has no effect on this
functionality. The change takes effect upon relay restart.
PRT2 REDUNDANCY — Determines if ports 2 and 3 operate in redundant or independent mode. If a license for PRP was
purchased, the options are None, Failover, and PRP. If a license for PRP was not purchased, the options are None and
Failover. In non-redundant mode (
REDUNDANCY set to None), ports 2 and 3 operate independently with their own MAC, IP,
and mask addresses. If
REDUNDANCY is set to Failover, the operation of ports 2 and 3 is as follows:
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are hidden
• Port 3 is in standby mode and does not actively communicate on the Ethernet network but monitors its link to the
Multilink switch. If port 2 detects a problem with the link, communications is switched to Port 3. Port 3 is, in effect,
acting as a redundant or backup link to the network for port 2. Once port 2 detects that the link between itself and the
switch is good and that communication is healthy for five minutes, then switching back to port 2 is performed. The
delay in switching back ensures that rebooted switching devices connected to the M60, which signal their ports as
active prior to being completely functional, have time to completely initialize themselves and become active. Once
port 2 is active again, port 3 returns to standby mode.
If
REDUNDANCY is set to PRP, the operation of ports 2 and 3 is as follows:
• Ports 2 and 3 use the port 2 MAC address, IP address, and mask
• The configuration fields for IP address and mask on port 3 are overwritten with those from port 2. This is visible on the
front panel but not displayed in the EnerVista software.
•Port 2
MCST ADDRESS field is visible
• The port 2 PTP function still uses only port 2 and the port 3 PTP function still uses only port 3. The relay still
synchronizes to whichever port has the best master. When ports 2 and 3 see the same master, as is typically the case
for PRP networks, the port with the better connectivity is used.
Behavior for GOOSE messages is as follows:
•If
REDUNDANCY is set to Failover or PRP, In order to transmit a GOOSE message on port 2, the CID file must be
configured to have the corresponding GSE element in both ConnectedAPs S2 and S3. In the EnerVista software, the
TxGOOSE PORT ASSIGNMENT needs to be "Ports-1,2,3" to transmit GOOSE on both ports 1 and 2, or "Ports-2,3" to have
GOOSE only on port 2, with failover/ PRP.
•If
REDUNDANCY is set to PRP, the port 2 configured GOOSE message is simultaneously transmitted on ports 2 and 3
•If
REDUNDANCY is set to failover and the port 2 link fails, then only the port 2 configured GOOSE message is transmitted
on port 3
PRT3 SUBNET IP MASK:
255.0.0.0
Range: standard IPV4 address format
PRT3 FUNCTION:
Enabled
Range: Enabled, Disabled
The two ports must be connected to completely independent LANs with no single point of failure, such as common
power supplies that feed switches on both LANs.
