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.

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
