• Signal names for selected analog channels
• Information e.g. trig on analog inputs
• Primary and secondary instrument transformer rating
• Over- or Undertrig: level and operation
• Over- or Undertrig status at time of trig
• CT direction
Binary:
• Signal names
• Status of binary input signals
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.

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 367.
