Cyclic reporting
SEMOD54417-158 v3
The cyclic reporting of measured value is performed according to chosen setting (
XRepTyp). The
measuring channel reports the value independent of magnitude or integral dead-band reporting.
In addition to the normal cyclic reporting the IED also report spontaneously when measured value
passes any of the defined threshold limits.

Magnitude dead-band supervision
SEMOD54417-163 v5
If a measuring value is changed, compared to the last reported value, and the change is larger than
the ±ΔY pre-defined limits that are set by user (
UDbRepIn), then the measuring channel reports
the new value to a higher level. This limits the information flow to a minimum necessary.
Figure
shows an example with the magnitude dead-band supervision. The picture is simplified:
the process is not continuous but the values are evaluated with a time interval of one execution
cycle from each other.
