appropriate. For example, pulse-On, on-time=100, off-time=300, count=5 would give 5 positive 100
ms pulses, 300 ms apart.
For description of the DNP3 protocol implementation, refer to the Communication manual.
12.10.3 Setting guidelines
AUTOBITS function block has one setting, (Operation: On/Off) enabling or disabling the function.
These names will be seen in the DNP3 communication management tool in PCM600.

12.11.2 Application
Single command, 16 inputs (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.

normally carried out by sending a pulse to the binary outputs of the IED. Figure
