Section 17
Logic
Settable time limits for warning and alarm are provided. The time limit for overflow indication
is fixed to 999999.9 seconds.
17.12.3 Setting guidelines
The settings
resolution of the settings depends on the level of the values defined.
A resolution of 10 ms can be achieved when the settings are defined within the range
1.00 second ≤ tAlarm ≤ 99 999.99 seconds
1.00 second ≤ tWarning ≤ 99 999.99 seconds.
If the values are above this range, the resolution becomes lower due to the 32 bit float
representation
99 999.99 seconds < tAlarm ≤ 999 999.0 seconds
99 999.99 seconds < tWarning ≤ 999 999.0 seconds
The limit for the overflow supervision is fixed at 999999.9 seconds.
17.13 Comparator for integer inputs - INTCOMP
17.13.1 Identification
Function description
Comparison of integer values
17.13.2 Application
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.
17.13.3 Setting guidelines
For proper operation of comparison the set value should be set within the range of ± 2 ×10
Setting procedure on the IED:
EnaAbs : This setting is used to select the comparison type between signed and absolute
values.
Absolute : Comparison is performed on absolute values of input and reference values
•
Signed : Comparison is performed on signed values of input and reference values.
•
RefSource : This setting is used to select the reference source between input and setting for
comparison.

tAlarm and tWarning are user settable limits defined in seconds. The achievable
tAlarm and tWarning are independent settings, that is, there is no
Note that
tAlarm > tWarning .
