those parts of the logic configuration that do not need
extensive command receiving functionality (for example,
SCSWI). In this way, simple commands can be sent directly
to the IED outputs, without confirmation. Confirmation (status)
of the result of the commands is supposed to be achieved by
other means, such as binary inputs and SPGGIO function
blocks. The commands can be pulsed or steady.
AutomationBits, command function for DNP3.0 AUTOBITS
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).
Single command, 16 signals
The IEDs can receive commands either from a substation
automation system or from the local HMI. The command
function block has outputs that can be used, for example, to
control high voltage apparatuses or for other user defined
functionality.
7. Logic
Configurable logic blocks
A number of logic blocks and timers are available for the user
to adapt the configuration to the specific application needs.
• OR function block.
• INVERTER function blocks that inverts the input signal.
• PULSETIMER function block can be used, for example, for
pulse extensions or limiting of operation of outputs, settable
pulse time.
• GATE function block is used for whether or not a signal
should be able to pass from the input to the output.
• XOR function block.
• LOOPDELAY function block used to delay the output signal
one execution cycle.
• TIMERSET function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a settable
time delay.
• AND function block.
• SRMEMORY function block is a flip-flop that can set or
reset an output from two inputs respectively. Each block
has two outputs where one is inverted. The memory setting
controls if the block's output should reset or return to the
state it was, after a power interruption. Set input has
priority.
• RSMEMORY function block is a flip-flop that can reset or
set an output from two inputs respectively. Each block has
two outputs where one is inverted. The memory setting
controls if the block's output should reset or return to the
state it was, after a power interruption. RESET input has
priority.
Fixed signal function block
The Fixed signals function (FXDSIGN) generates a number of
pre-set (fixed) signals that can be used in the configuration of
an IED, either for forcing the unused inputs in other function
blocks to a certain level/value, or for creating certain logic.
8. Monitoring
Measurements CVMMXN, CMMXU, VNMMXU, VMMXU,
CMSQI, VMSQI
The measurement functions are used to get on-line
information from the IED. These service values make it
possible to display on-line information on the local HMI and
on the Substation automation system about:
• measured voltages, currents, frequency, active, reactive
and apparent power and power factor
• primary and secondary phasors
• positive, negative and zero sequence currents and
voltages
• mA, input currents
• pulse counters
Event counter CNTGGIO
Event counter (CNTGGIO) has six counters which are used for
storing the number of times each counter input has been
activated.
Disturbance report DRPRDRE
Complete and reliable information about disturbances in the
primary and/or in the secondary system together with
continuous event-logging is accomplished by the disturbance
report functionality.
Disturbance report DRPRDRE, always included in the IED,
acquires sampled data of all selected analog input and binary
signals connected to the function block with a, maximum of
40 analog and 96 binary signals.
The Disturbance report functionality is a common name for
several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great
flexibility regarding configuration, starting conditions,
recording times, and large storage capacity.
