Web HMI

The WHMI is the only user access service in the protection device. To provide
encryption and secure identification in the communication to the WHMI, the device
supports HTTPS protocol. In this case plain HTTP connection request is
automatically changed to HTTPS. In case of HTTPS access the Web client must
support HTTPS via TLS 1.0 or TLS 1.1/1.2. The WHMI is verified with Internet Explorer
11.0.
WHMI offers several functions.
• Programmable virtual LEDs and event lists
• System supervision
• Parameter settings
• Measurement display
• Disturbance records
• Fault records
• Phasor diagram
• Single line diagram
• Report summary
The WHMI can be accessed locally and remotely.
• Locally by connecting the laptop to the IED via the local communication port.
• Remotely over LAN/ WAN.
