Figure 140 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 140 shows a close operation. An open breaker
operation is performed in a similar way but without the synchro-check condition.

Figure
141 and figure 142 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.
