Communication Protocol Manual
The IEC 60870-5-103 disturbance recorder file directory can be requested by the
client at any time by asking GI data. In addition, the disturbance recorder file directory
should 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 could also mean that
a disturbance recorder file is deleted from the native disturbance recorder file system.
Disturbance recorder files can be deleted by the IEC 60870-5-103 master. The
recorder file is deleted by the IED after it has been sent to the IEC 60870-5-103 master
according to the standard. Disturbance recorder files can also be deleted from
PCM600, WHMI, LHMI or IEC 60870-5-103 client.
The IED stores only one instance of disturbance records in memory
for IEC 60870-5-103 protocol. Reading a complete recording deletes
it from the common database. Thus, it is recommended to use only one
protocol client to read disturbance records via IEC 60870-5-103
protocol.

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.
