REX640 overview

Figure 6: Example of a switchgear HMI navigation page

The SHMI has a navigation page which presents the physical switchgear lineup

installation and indicates the status of each REX640 within the system. The area

presenting a single switchgear bay has a small user-configurable bay overview

section and a virtual Home button showing the status of the connected relay. By

tapping the selected bay overview area, the SHMI connects with the related REX640

and works as normal LHMI for that relay.
