interruption, or be reset. The function also propagates
the time stamp and the quality of the input signal.
• 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
the time stamp and the quality of the input signal.
• 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 the time stamp and the quality of the
input signal.
• XORQT XOR function block. The function also
propagates the time stamp and the quality of the
input signals. Each block has two outputs where one is
inverted.
Extension logic package
The logic extension block package includes additional
trip matrix logic and configurable logic blocks.
Fixed signal function block FXDSIGN
The Fixed signals function (FXDSIGN) has nine 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. Boolean, integer, floating point, string
types of signals are available.
One FXDSIGN function block is included in all IEDs.
Elapsed time integrator with limit transgression and
overflow supervision TEIGAPC
The Elapsed time integrator function (TEIGAPC) is a
function that accumulates the elapsed time when a
given binary signal has been high.
The main features of TEIGAPC
• Applicable to long time integration (≤999 999.9
seconds).
• Supervision of limit transgression conditions and
overflow.
• Possibility to define a warning or alarm with the
resolution of 10 milliseconds.
• Retaining of the integration value.
• Possibilities for blocking and reset.
• Reporting of the integrated time.
Boolean to integer conversion, 16 bit B16I
Boolean to integer conversion, 16 bit (B16I) is used to
transform a set of 16 boolean (logical) signals into an
integer.

Boolean to integer conversion with logical node
representation, 16 bit BTIGAPC
Boolean to integer conversion with logical node
representation, 16 bit (BTIGAPC) is used to transform a
set of 16 boolean (logical) signals into an integer. The
block input will freeze the output at the last value.
Integer to Boolean 16 conversion IB16
Integer to boolean 16 conversion function (IB16) is used
to transform an integer into a set of 16 boolean (logical)
signals.
Integer to Boolean 16 conversion with logic node
representation ITBGAPC
Integer to boolean conversion with logic node
representation function (ITBGAPC) is used to transform
an integer which is transmitted over IEC 61850 and
received by the function to 16 boolean (logic) output
signals.
Comparator for integer inputs INTCOMP
The function gives the possibility to monitor the level of
integer values in the system relative to each other or to
a fixed value. It is a basic arithmetic function that can be
used for monitoring, supervision, interlocking and other
logics.
Comparator for real inputs REALCOMP
The function gives the possibility to monitor the level of
real value signals in the system relative to each other or
to a fixed value. It is a basic arithmetic function that can
be used for monitoring, supervision, interlocking and
other logics.

17. 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
• measured analog values from merging units
• primary phasors
• positive, negative and zero sequence currents and
voltages
• mA, input currents
• pulse counters
Supervision of mA input signals
The main purpose of the function is to measure and
process signals from different measuring transducers.
Many devices used in process control represent various
