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.
•
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.

matrix logic and configurable logic blocks.
Fixed signal function block FXDSIGN
M15322-3 v15
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
GUID-2D64874A-F266-4251-8EED-E813F40513D7 v3
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
SEMOD175725-4 v5
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
SEMOD175781-4 v8
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
SEMOD158373-5 v7
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
SEMOD158421-5 v9
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
GUID-A93564FA-0017-4939-A9C1-095DA0FD9832 v1
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
GUID-E17A88D7-D095-4F36-9CD5-64EBFD2A1DEA v1
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.
Hold Maximum and Minimum of Input HOLDMINMAX
GUID-7DA0AA9A-CCEA-4467-B67E-45B9C1DC145A v1
Hold minimum and maximum of input (HOLDMINMAX)
function will acquire, compare and hold the minimum and
maximum values of INPUT as soon as the START input
goes to 1, the outputs are updated as long as the START is
1. After START goes to 0, the last updated value is stored.
The outputs are reset when the RESET is 1.
Converter integer to real INT_REAL
GUID-B5E646B7-07AC-448E-B75E-773452157369 v1
The converter integer to real (INT_REAL) function can be
used to convert integer to real values.
Definable constant for logic function CONST_INT
GUID-4EF2869F-48F1-4B7B-B99B-FEAAC9431A9B v1
The definable constant for logic function CONST_INT can
be used to provide a constant output in an integer format
based on the set value in PST.
Analog input selector for integer values INTSEL
GUID-567B1181-BDE7-497B-8020-FDB798F0FCB5 v1
Analog input selector for integer values (INTSEL) selects
one out of eight possible integer inputs. Each input
(INPUTx) has its dedicated select input (SELx). The
function provides the output for the value of the selected
input, and its respective select number (INSEL).
If more than one input is selected, the output will be the
lowest in order INPUT value. If inputs are not selected, the
select value number shall be 0.
Definable limiter LIMITER
GUID-BD0E0AB5-03AD-469E-AE25-D92BD9555FC5 v1
The definable limiter (LIMITER) function can be used to limit
the output values within the minimum and maximum limits
set in the PST. If the input is outside the set range then the
