General start matrix block SMAGAPC
The Start Matrix (SMAGAPC) merges start and directional
output signals from different application functions and creates a
common start and directional output signal (
STDIR
) to be
connected to the Trip function.
The idea is to provide general start and directional information
for the 61850 trip logic data model SMPPTRC.
IEC 61850 naming and description:
• SMAGAPC for Start Matrix function
• SMPPTRC for Trip function
• STARTCOMB for Start Combination function
Trip matrix logic TMAGAPC
The trip matrix logic TMAGAPC function is used to route trip
signals and other logical output signals to different output
contacts on the IED.
The trip matrix logic function has 3 output signals and these
outputs can be connected to physical tripping outputs
according to the specific application needs for settable pulse or
steady output.
Group alarm logic function ALMCALH
The group alarm logic function (ALMCALH) is used to route
several alarm signals to a common indication, LED and/or
contact, in the IED.
Group warning logic function WRNCALH
The group warning logic function (WRNCALH) is used to route
several warning signals to a common indication, LED and/or
contact, in the IED.
Group indication logic function INDCALH
The group indication logic function (INDCALH) is used to route
several indication signals to a common indication, LED and/or
contact, in the IED.
Basic configurable logic blocks
The basic configurable logic blocks do not propagate the time
stamp and quality of signals (have no suffix QT at the end of
their function name). A number of logic blocks and timers are
always available as basic for the user to adapt the configuration
to the specific application needs. The list below shows a
summary of the function blocks and their features.
These logic blocks are also available as part of an extension
logic package with the same number of instances.
• AND function block. The AND function is used to form general
combinatory expressions with boolean variables. The AND
function block has up to four inputs and two outputs. One of
the outputs is inverted.
• GATE function block is used for whether or not a signal
should be able to pass from the input to the output.
•
INVERTER function block that inverts the input signal to the
output.
• LLD function block. Loop delay used to delay the output
signal one execution cycle.
• OR function block. The OR function is used to form general
combinatory expressions with boolean variables. The OR
function block has up to six inputs and two outputs. One of
the outputs is inverted.
• PULSETIMER function block can be used, for example, for
pulse extensions or limiting of operation of outputs, settable
pulse time.
• 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, after a power interruption, the flip-flop resets or returns to
the state it had before the power interruption. RESET input
has priority.
• 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, after a power interruption, the flip-flop resets or returns to
the state it had before the power interruption. The SET input
has priority.
• TIMERSET function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a settable
time delay.
• XOR is used to generate combinatory expressions with
boolean variables. XOR has two inputs and two outputs. One
of the outputs is inverted. The output signal OUT is 1 if the
input signals are different and 0 if they are the same.
Configurable logic blocks Q/T
The configurable logic blocks QT propagate the time stamp and
the quality of the input signals (have suffix QT at the end of their
function name).
The function blocks assist the user to adapt the IEDs'
configuration to the specific application needs. The list below
shows a summary of the function blocks and their features.
• ANDQT AND function block. The function also propagates
the time stamp and the quality of input signals. Each block
has four inputs and two outputs where one is inverted.
• INDCOMBSPQT combines single input signals to group
signal. Single position input is copied to value part of
SP_OUT output. TIME input is copied to time part of
SP_OUT output. Quality input bits are copied to the
corresponding quality part of SP_OUT output.
• INDEXTSPQT extracts individual signals from a group
signal input. The value part of single position input is
