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 malfunction, 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 (U), 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.

Locating and using the single line diagram

It is possible to navigate the SLD screen using the up and down keys on the IED
keypad. The apparatus under control is highlighted as the user moves from symbol
to symbol using the keypad. An apparatus is opened using the green Ored Close
key and closed using the red I key.
