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.
Quality input bits are copied to the corresponding quality part
of SP_OUT output.
• INDEXTSPQT extracts individual signals from a group signal
input. Value part of single position input is copied to SI_OUT
output. Time part of single position input is copied to TIME
output. Quality bits in common part and indication part of
inputs signal is copied to the corresponding quality output.
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.
Boolean 16 to Integer conversion B16I
Boolean 16 to integer conversion function B16I is used to
transform a set of 16 binary (logical) signals into an integer.
Boolean 16 to Integer conversion with logic node
representation B16IFCVI
Boolean 16 to integer conversion with logic node
representation function B16IFCVI is used to transform a set of
16 binary (logical) signals into an integer. The block input will
freeze the output at the last value.
Integer to Boolean 16 conversion IB16A
Integer to boolean 16 conversion function IB16A is used to
transform an integer into a set of 16 binary (logical) signals.
Integer to Boolean 16 conversion with logic node
representation IB16FCVB
Integer to boolean conversion with logic node representation
function IB16FCVB is used to transform an integer to 16 binary
(logic) signals.
IB16FCVB function can receive remote values over IEC61850
when the operator position input PSTO is in position remote.
The block input will freeze the output at the last value.
Elapsed time integrator with limit transgression and overflow
supervision TEIGGIO
The function TEIGGIO is used for user defined logics and it can
also be used for different purposes internally in the IED . An
application example is the integration of elapsed time during the
measurement of neutral point voltage or neutral current at earth
fault conditions.
Settable time limits for warning and alarm are provided. The
time limit for overflow indication is fixed.
12. Monitoring
IEC61850 generic communication I/O function SPGGIO
IEC61850 generic communication I/O functions SPGGIO is
used to send one single logical signal to other systems or
equipment in the substation.
IEC61850 generic communication I/O function 16 inputs
SP16GGIO
IEC 61850 generic communication I/O functions 16 inputs
SP16GGIO function is used to send up to 16 logical signals to
other systems or equipment in the substation.
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
• primary and secondary phasors
• current sequence components
• voltage sequence components
Event counter CNTGGIO
Event counter CNTGGIO has six counters which are used for
storing the number of times each counter input has been
activated.
Event counter with limit supervison L4UFCNT
The 12 Up limit counter L4UFCNT provides a settable counter
with four independent limits where the number of positive
and/or negative flanks on the input signal are counted against
the setting values for limits. The output for each limit is activated
when the counted value reaches that limit.
Overflow indication is included for each up-counter.
Disturbance report DRPRDRE

primary and/or in the secondary system together with
