• 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 must be
Enabled for the input signal to activate the output
with the appropriate 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. The SET input
has priority if both SET and RESET inputs are
operated simultaneously.
• 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. The RESET
input has priority if both SET and RESET are
operated simultaneously.
Configurable logic Q/T
A number of logic blocks and timers with the
capability to propagate timestamp and quality of the
input signals are available. The function blocks
assist the user to adapt the IEDs configuration to
the specific application needs.
• ORQT function block that also propagates
timestamp and quality of input signals.
• INVERTERQT function block that inverts the
input signal and propagates timestamp and
quality of input signal.
• PULSETIMERQT function block can be used, for
example, for pulse extensions or limiting of
operation of outputs. The function also
propagates timestamp and quality of input signal.
• XORQT function block. The function also
propagates timestamp and quality of input signals.
• TIMERSETQT function has pick-up and drop-out
delayed outputs related to the input signal. The
timer has a settable time delay. The function also
propagates timestamp and quality of input signal.
• ANDQT function block. The function also
propagates timestamp and quality of input signals.
• SRMEMORYQT 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 after a power interruption should return to
the state before the interruption, or be reset. The
function also propagates timestamp and quality of
input signal.
• RSMEMORYQT 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 after a power interruption should return to
the state before the interruption, or be reset. The
function also propagates timestamp and quality of
input signal.
• INVALIDQT function which sets quality invalid of
outputs according to a "valid" input. Inputs are
copied to outputs. If input VALID is 0, or if its
quality invalid bit is set, all outputs invalid quality
bit will be set to invalid. The timestamp of an
output will be set to the latest timestamp of
INPUT and VALID inputs.
• 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. State
input bits are copied to the corresponding state
part of SP_OUT output. If the state or value on
the SP_OUT output changes, the Event bit in the
