Line distance protection REL670
Version 2.2
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.
Hold Maximum and Minimum of Input HOLDMINMAX
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
The converter integer to real (INT_REAL) function can be
used to convert integer to real values.
Definable constant for logic function CONST_INT
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
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
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
value OUTLIMIT is set to 1 to indicate the output value is
limited.
Absolute value ABS
The absolute value (ABS) function gives the absolute value
of the input.
Polar to rectangular converter POL_REC
The polar to rectangular converter (POL_REC) function
gives the possibility to convert an input values in polar form
to a rectangular form.
Radians to degree angle converter RAD_DEG
The radians to degree angle converter (RAD_DEG) function
gives the possibility to convert an input value from radian
angles to degree angles.
Definable constant for logic function CONST_REAL
The definable constant for logic function (CONST_REAL)
can be used to provide a constant output in an real format
based on the set value in PST.
Analog input selctor for real values REALSEL
Analog input selector for real values (REALSEL) function
selects one out of eight possible real 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
