protection signal, triggered externally or triggered periodically. In
this case the disturbance recorder file would not correspond to any
particular fault detected by the IED.
The IEC 60870-5-103 directory information octet SOF, TP, TEST and OTEV bits
are not supported by the IED's native disturbance recorder file system. These bits
are therefore always set to 0. The TM bit is however supported.
The IEC 60870-5-103 disturbance recorder directory structure only allows up to
eight disturbance recorder files to be available in the IED. If the IED's native
disturbance recorder file system contains more than eight disturbance recorder
files, only the 8 latest files are accessible through IEC 60870-5-103 protocol.
The IEC 60870-5-103 disturbance recorder file directory can be requested by the
client at any time. In addition, should the disturbance recorder file directory be sent
spontaneously by the IED (through Class 1 report) to the client if the directory
structure changes. A change in the directory structure normally means that a new
disturbance recorder file has been captured and stored. It also could mean that a
disturbance recorder file is deleted from the native disturbance recorder file system.
Disturbance recorder files can not be deleted by the IEC 60870-5-103 client
according to the standard. Disturbance recorder files could anyhow be deleted from
LHMI or Ethernet.

Disturbance recorder channel identification

IEC 60870-5-103 defines channels (analog data) and tags (digital data) to be
transferred from a disturbance recorder file. The IEC 60870-5-103 file transfer is
random access, meaning that the client can select exactly what information to read
from the file.
The standard defines the identification, ACC (actual channel), for eight channels,
numbered 1...8. For example, when a client requests channel 1, it always means
Phase current L1. The IED supports all the eight IEC 60870-5-103 standard
channel numbers and in addition defines some private channel numbers. Private
channel numbers starts from ACC 64 as is defined by the standard.
