620 series Cyber Security Deployment Guideline

WHMI is disabled by default, and has to be activated in the protection relay configuration. As secure communication is enabled by default, the WHMI must be accessed from a Web browser using the HTTPS protocol.

  1. To enable the WHMI, select Main menu > 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.
Tip: To establish a remote WHMI connection to the protection relay, contact the network administrator to check the company rules for IP and remote connections.
Note: 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.
