15.10.2 Application
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 298 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
298 shows a close operation. An open breaker operation is performed
in a similar way but without the synchro-check condition.

Figure 299 and figure 300 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.
