Introduction
AutomationBits function for DNP3 (AUTOBITS) is used within PCM600 to get into
the configuration of the commands coming through the DNP3 protocol. The
AUTOBITS function plays the same role as functions GOOSEBINRCV (for IEC
61850) and MULTICMDRCV (for LON).
Principle of operation
AutomationBits 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.
