Physical and virtual Home buttons

On the SHMI navigation page, the virtual Home button shows the status of each
relay as it would be shown with the physical Home button on a normal LHMI panel.
In normal situations, the virtual Home button shows a steady green light. All other
situations in which the relay requires operator's attention are indicated with a
flashing light, a red light or a combination of these.
SHMI's physical Home button has two operation modes.
• On the SHMI navigation page, the Home button indicates the combined status of
all connected relays. If multiple relays have different statuses, the Home button
shows the indication with the highest priority.
• On the HMI view, the Home button indicates the status of the respective relay as
described in

navigation page can be scrolled by swiping the screen horizontally or by pressing
the physical Home button to move the page from left to right one bay overview at a
time.
Bay overview area is the configured view for one relay. It may show static or dynamic
information but all control operations are disabled. The whole bay overview area
works as a navigation point to the relay's HMI view. Tapping this area opens the HMI
view of the respective relay.
Panel lineup overview shows the position of the navigation page by highlighting the
