Figure 186 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
operation is performed in a similar way but without the synchro-check condition.
