of the value to the higher levels depends on the selected reporting mode. The
following basic reporting modes are available:
•
Cyclic reporting (
Cyclic
)
•
Amplitude dead-band supervision (
Dead band
)
•
Integral dead-band supervision (
Int deadband
)
Cyclic reporting
The cyclic reporting of measured value is performed according to chosen setting
(
XRepTyp
). The measuring channel reports the value independent of amplitude 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.

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