5. Check the default settings in the SCL Import view and change them if needed.
The default settings in the SCL Import dialog should be correct in most cases.
6. Click Import to import the SCD file.
7. Check the IP address on the IEC 61850 subnetwork and change it if needed.
When the SCD file is directly exported from PCM600, it uses the IP address of
the PCM600 computer, not that of COM600S.
The communication towards the protection relays is now ready. For information on
how to finalize the single-line diagram and enable parameter setting through
COM600S HMI, see the COM600S documentation.

Using Web HMI

Connection to WHMI can be established using different communication card ports.
X0/HMI has always WHMI enabled and is intended to be used with HMI. For other
ports, WHMI is enabled by default and can be disabled in the protection relay
configuration. As only secure communication is supported for the WHMI, it must be
accessed from a Web browser using the HTTPS protocol. Three WHMI sessions at a
time are supported.
1. To enable the WHMI, select Configuration/HMI/Web HMI mode via the
LHMI.
2. To disable the WHMI for station ports, select Communication/Protocols/
Network1/HTTPS and Communication/Protocols/Network2/HTTPS via
the LHMI and set the parameter to "Off".
3. Reboot the relay for the change to take effect.
4. Log in with the proper user rights to use the WHMI.
To establish a remote WHMI connection to the protection relay,
contact the network administrator to check the company rules
for IP and remote connections.
Disable the Web browser proxy settings or make an exception to
the proxy rules to allow the protection relay's WHMI
connection, for example, by including the relay's IP address in
Internet Options/Connections/LAN Settings/Advanced/
Exceptions.
The WHMI write access can be limited with the parameter
HTTPS write access in Configuration/Authorization/
Network1.
