A total of two sets of recorded data are saved in data banks
Recorded data 2 . Data bank Recorded data 1 holds the most recent recorded data
and the older data is moved into the data bank
occurs. When all two banks have data and a new triggering occurs, the latest
data is placed into bank
is overwritten by the data from bank
It is possible to reset corresponding recorded data by either:
• activating LHMI parameter Clear/Clear/IFPTOCx reset = 1 ("Clear") or
• writing directly by MMS LD0.IFPTRCx.RcdRs.Oper.ctlVal = 1 ("Clear")"

Activation of OPERATE output results to automatic triggering of fault
recording.
