The WHMI provides a remote user interface on a common Internet browser via Ethernet link. The

functionality is explained in the User manual.

Basic operation of the WHMI is configured by the WEBSERVER function block.

After storing an operation record or waveform record, a background function updates an internal

table of matching records: If the time stamps of an operation record and a waveform record are

within ±20 ms of each other, they are assumed to describe the same switching operation. In WHMI,

this information is used for creating hyperlinks, to allow directly jumping between views.
