20. Local HMI
The relay is available with two optional displays, a large one and
a small one. The large display is suited for relay installations
where the front panel user interface is frequently used and a
single line diagram is required. The small display is suited for
remotely controlled substations where the relay is only
occasionally accessed locally via the front panel user interface.
Both LCD displays offer front-panel user interface functionality
with menu navigation and menu views. However, the large
display offers increased front-panel usability with less menu
scrolling and improved information overview. In addition, the
large display includes a user-configurable single line diagram
(SLD) with position indication for the associated primary
equipment. Depending on the chosen standard configuration,
the relay displays the related measuring values, apart from the
default single line diagram. The SLD view can also be accessed
using the Web browser-based user interface. The default SLD
can be modified according to user requirements by using the
Graphical Display Editor in PCM600. The user can create up to
10 SLD pages.
The local HMI includes a push button (L/R) for local/remote
operation of the relay. When the relay is in the local mode, it can
be operated only by using the local front panel user interface.
When the relay is in the remote mode, it can execute
commands sent from a remote location. The relay supports the
remote selection of local/remote mode via a binary input. This
feature facilitates, for example, the use of an external switch at
the substation to ensure that all relays are in the local mode
during maintenance work and that the circuit breakers cannot
be operated remotely from the network control center.
