Cyclic reporting
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
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 (XDbRepInt), then the
measuring channel reports the new value to a higher level. This limits the information
flow to a minimum necessary. Figure
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.
