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.
