20. Local HMI
The IED is available with two optional
displays, a large one and a small one. The
large display is suited for IED 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
IED 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 IED 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 local HMI includes a push button (L/R)
for local/remote operation of the IED. When
the IED is in the local mode, the IED can be
operated only by using the local front panel
user interface. When the IED is in the remote
mode, the IED can execute commands sent
from a remote location. The IED 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 IEDs are in the
local mode during maintenance work and
that the circuit breakers cannot be operated
remotely from the network control centre.
