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.
16. Monitoring
Measurements CVMMXN, CMMXU, VNMMXU,
VMMXU, CMSQI, VMSQI
M12024-3 v9
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
M16054-3 v2
The main purpose of the function is to measure and
process signals from different measuring transducers.
Many devices used in process control represent various
parameters such as frequency, temperature and DC
battery voltage as low current values, usually in the
range 4-20 mA or 0-20 mA.
Alarm limits can be set and used as triggers, e.g. to
generate trip or alarm signals.
The function requires that the IED is equipped with the
mA input module.
Disturbance report DRPRDRE
M12153-3 v14
Complete and reliable information about disturbances in
the primary and/or in the secondary system together
with continuous event-logging is accomplished by the
disturbance report functionality.
Disturbance report (DRPRDRE), always included in the
IED, acquires sampled data of all selected analog input
and binary signals connected to the function block with
a maximum of 40 analog and 352 binary signals.
The Disturbance report functionality is a common name
for several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
• Fault locator
• Settings information
