(for LON).AUTOBITS function block have 32 individual outputs which each can be mapped as a
Binary Output point in DNP3. The output is operated by a "Object 12" in DNP3. This object
contains parameters for control-code, count, on-time and off-time. To operate an AUTOBITS
output point, send a control-code of latch-On, latch-Off, pulse-On, pulse-Off, Trip or Close. The
remaining parameters are regarded as 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.

13.11.2 Application
M12445-3 v3
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
167 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
167 shows a
close operation. An open breaker operation is performed in a similar way but without the
synchro-check condition.
