12.9.2 Application
M12445-3 v3
Single command, 16 signals (SINGLECMD) is a common function and always
included in the IED.
The IEDs may be provided with a function to receive commands either from a
substation automation system or from the local HMI. That receiving function block
has outputs that can be used, for example, to control high voltage apparatuses in
switchyards. For local control functions, the local HMI can also be used. Together
with the configuration logic circuits, the user can govern pulses or steady output
signals for control purposes within the IED or via binary outputs.
Figure
115 shows an application example of how the user can connect
SINGLECMD via configuration logic circuit to control a high-voltage apparatus.
This type of command control is normally carried out by sending a pulse to the
binary outputs of the IED. Figure 115 shows a close operation. An open breaker
operation is performed in a similar way but without the synchro-check condition.
