Operation: turning the function operation Enabled/Disabled.
There are two settings for every command output (totally 8):
Latchedx: decides if the command signal for output x is Latched (steady) or Pulsed.
tPulsex: if Latchedx is set to Pulsed, then tPulsex will set the length of the pulse (in
seconds).

10.9.2 Application
The AUTOBITS function block (or the automation bits function block) is used within
PCM600 in order to get into the configuration the commands coming through the DNP3
protocol.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.
See the communication protocol manual for a detailed description of the DNP3 protocol
10.9.3 Setting guidelines
AUTOBITS function block has one setting, (Operation: Enabled/Disabled) enabling or
disabling the function. These names will be seen in the DNP communication
configuration tool in PCM600.
