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 293 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 293 shows a close operation. An open breaker operation is performed
in a similar way but without the synchro-check condition.
