About this chapter
This chapter describes the various control and supervision functions available in the
HMI. In particular, how the single line diagram available on the display can be used for
this purpose. It also describes the Selector switch function available under the control
menu.

Overview

The control menu in the HMI includes the Single line diagram, Single command and
Selector switch functions.
The Single Line Diagram (SLD) is used to control and supervise the bay by allowing
the operator to close and open apparatuses using keys on the front panel of the IED.
This is primarily intended as a backup for higher level control systems. If for example
MicroSCADA were to go out of service, then bay level switches and circuit breakers
can be controlled directly from the HMI.
The Single command function is used to view LON interlocking data and is only
visible if LON is configured and used in the system.
The Selector Switch function is configured in the PCM600 tool and the switch position
can be changed in the HMI. The selector switch has the same function as a rotating
switch with up to 32 positions. Each position is configured in the PCM600 to match a
certain application. Each position number corresponds to the equivalent position of a
rotating switch. It is only visible if it has been configured in the PCM600.

Read measured values and check apparatus status

In the single line diagram a number of measured quantities are displayed. These are
normally system voltage (V), system current (I), active power (P) and reactive power
(Q). They are displayed on the right hand side of the SLD graphic. The quantities
shown can be configured in PCM600 and may therefore not always have the same
appearance in different IEDs.
