Recorded data

All the information required for a later fault analysis is recorded to 21FL recorded data. In
the protection relay, recorded data is found in Monitoring/Recorded data/Other
protection/S21FL.
The function has also monitored data values which are used for the read-out of continuous
calculation values. The cross reference table shows which of the recorded data values are
available as continuous monitoring values during a fault.
