Channel number used for the remaining 32 analog signals are numbers in the private range
64 to 95.
Binary signals, 96-channels: for each channel the user can specify a FUNCTION TYPE
and an INFORMATION NUMBER.
Disturbance upload
All analog and binary signals that are recorded with disturbance recorder can be reported
to the master. The last eight disturbances that are recorded are available for transfer to the
master. A successfully transferred disturbance (acknowledged by the master) will not be
reported to the master again.
When a new disturbance is recorded by the IED a list of available recorded disturbances
will be sent to the master, an updated list of available disturbances can be sent whenever
something has happened to disturbances in this list. For example, when a disturbance is
deleted (by other client, for example, SPA) or when a new disturbance has been recorded
or when the master has uploaded a disturbance.
Deviations from the standard
Information sent in the disturbance upload is specified by the standard; however, some of
the information are adapted to information available in disturbance recorder in the IED
series.
This section describes all data that is not exactly as specified in the standard.
ASDU23
In ‘list of recorded disturbances’ (ASDU23) an information element named SOF (status
of fault) exists. This information element consists of 4 bits and indicates whether:
• Bit TP: the protection equipment has tripped during the fault
• Bit TM: the disturbance data are currently being transmitted
• Bit TEST: the disturbance data have been recorded during normal operation or test
mode.
• Bit OTEV: the disturbance data recording has been initiated by another event than
pick-up
The only information that is easily available is test-mode status. The other information is
always set (hard coded) to:
