Figure 87 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
87 shows a close operation. An open breaker
operation is performed in a similar way but without the synchro-check condition.

Figure 88 and figure 89 show other ways to control functions, which require steady
On/Off signals. Here, the output is used to control built-in functions or external
devices.
