In this mode of operation, the reporting interval will be cyclic like in reporting type
cyclic. This cyclic time has three options: 5sec, 30 sec and 1 min.
Additionally, if a measuring value has changed from the last reported value, and
the change is larger than ±ΔY predefined limits that are set by user (XDbRepInt),
then the measuring channel reports the new value to a higher level immediately
irrespective of cyclic trigger. See Figure
262 for example.
