Bay control REC670 2.1 IEC
• XOR function block. 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.
Logic rotating switch for function selection and LHMI
presentation SLGAPC
The logic rotating switch for function selection and
LHMI presentation SLGAPC (or the selector switch
function block) is used to get an enhanced selector
switch functionality compared to the one provided by a
hardware selector switch. Hardware selector switches
are used extensively by utilities, in order to have
different functions operating on pre-set values.
Hardware switches are however sources for
maintenance issues, lower system reliability and an
extended purchase portfolio. The selector switch
function eliminates all these problems.
Selector mini switch VSGAPC
The Selector mini switch VSGAPC function block is a
multipurpose function used for a variety of applications,
as a general purpose switch.
VSGAPC can be controlled from the menu or from a
symbol on the single line diagram (SLD) on the local HMI.
Fixed signal function block
The Fixed signals function FXDSIGN generates 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 16 to integer conversion function B16I is used to
transform a set of 16 binary (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 binary (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 binary coded (logic)
output signals.
ITBGAPC function can only receive remote values over
IEC 61850 when the R/L (Remote/Local) push button on
the front HMI, indicates that the control mode for the
operator is in position R (Remote i.e. the LED adjacent
to R is lit ), and the corresponding signal is connected to
the input PSTO ITBGAPC function block. The input
BLOCK will freeze the output at the last received value
and blocks new integer values to be received and
converted to binary coded outputs.
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.
12. 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:
