The configuration file is a mandatory file containing information needed to interpret
the data file. For example sampling rate, number of channels, system frequency,
channel info etc.
The data file, which also is mandatory, containing values for each input channel for
each sample in the record (scaled value). The data file also contains a sequence number
and time stamp for each set of samples.
15.12.2.2 IEC 60870-5-103
The communication protocol IEC 60870-5-103 may be used to poll disturbance
recordings from the IED to a master (station HSI). The standard describes how to
handle 8 disturbance recordings, 8 analog channels (4 currents and 4 voltages) using
the public range and binary signals.
The last 8 recordings, out of maximum 100, are available for transfer to the master.
When the last one is transferred and acknowledged new recordings in the IED will
appear, in the master points of view (even if they already where stored in the IED).
To be able to report 40 analog channels from the IED using IEC 60870-5-103 the first
8 channels are placed in the public range and the next 32 are placed in the private
range. To comply the standard the first 8 must be configured according to table
601.
