• 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.

15. 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:
• 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
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
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
• Settings information
The Disturbance report function is characterized by
great flexibility regarding configuration, starting
conditions, recording times, and large storage capacity.
A disturbance is defined as an activation of an input to
the AnRADR or BnRBDR function blocks, which are set to
trigger the disturbance recorder. All connected signals
from start of pre-fault time to the end of post-fault time
will be included in the recording. Disturbance record will
have visible settings from all function instances that are
configured in the application configuration tool.
Every disturbance report recording is saved in the IED in
the standard Comtrade format as a reader file HDR, a
configuration file CFG, and a data file DAT. The same
applies to all events, which are continuously saved in a
ring-buffer. The local HMI is used to get information
about the recordings. The disturbance report files can
