Connecting to 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. Reboot the relay for the change to take effect.
3. 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.

Logging in

1. Open a Web browser.
2. Type the protection relay's IP address in the address bar and press ENTER.
3. Type the username.
4. Type the password.
