11.10.6 Operation principle
Automation bits function (AUTOBITS) has 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 will be regarded were
appropriate. ex: pulse-On, on-time=100, off-time=300, count=5 would give 5 positive
100 ms pulses, 300 ms apart.
There is a BLOCK input signal, which will disable the operation of the function, in the
same way the setting
Operation : Enabled/Disabled does. That means that, upon activation
of the BLOCK input, all 32 CMDBITxx outputs will be set to 0. The BLOCK acts like an
overriding, the function still receives data from the DNP3 master. Upon deactivation of
BLOCK, all the 32 CMDBITxx outputs will be set by the DNP3 master again,
momentarily. For AUTOBITS , the PSTO input determines the operator place. The
command can be written to the block while in “Remote”. If PSTO is in “Local” then no
change is applied to the outputs.
For description of the DNP3 protocol implementation, refer to DNP3 communication
protocol manual.

11.11.1 Functionality
I103CMD is a command function block in control direction with pre-defined output
signals. The signals are in steady state, not pulsed, and stored in the IED in case of restart.
