Disturbance recorder channels are the physical measurement inputs to the IED. It
depends on the IED type if all the disturbance recorder channel signals are
available or not. The IED may measure voltages either between phase and ground
or between phases. The contents in ACC 5...8 and 69...71 are coupled directly to
these voltage measurements.

Disturbance recorder tags identification

According to the IEC 60870-5-103 standard the disturbance recorder tags (digital
signals) are identified by the same function type/information number combination
that corresponds to the signal in the normal IEC 60870-5-103 Class 1 event
transfer. This rule is followed by the IED if the indication signal in question is
solely connected to the disturbance recorder digital channel. If the signal, for
example, is OR-ed together with other internal digital signals or if the signal is not
present in the normal IEC 60870-5-103 Class 1 data, then the tag identification is
always:
Function type = 5
Information number = disturbance recorder digital channel number

Disturbance recorder transfer

When the IEC 60870-5-103 client selects a disturbance recorder channel to be
transferred, the corresponding disturbance recorder channel data is internally
fetched from the IED's native disturbance recorder file, cached and converted into
IEC 60870-5-103 format. This operation may take some time depending on the size
of the disturbance recorder file.
Once an IEC 60870-5-103 disturbance recorder channel or tag transmission is in
progress, it can be performed till the end, even if the native original disturbance
recorder file simultaneously is deleted from the system.
