Technical manual
<Number of information elements> is defined by index of first input not connected.
Example: Input1, Input2, and Input4 are connected, Input3 is not connected.
<Number of information elements> will be 3 (Input3 NOT connected) -1 = 2, that
is, only Input1 and Input2 will be transmitted.
Disturbance recordings
The following elements are used in the ASDUs (Application Service Data Units)
defined in the standard.
Analog signals, 40-channels: the channel number for each channel has to be
specified. Channels used in the public range are 1 to 8 and with:
•
I
connected to channel 1 on disturbance function block A1RADR
L1
•
I
connected to channel 2 on disturbance function block A1RADR
L2
•
I
connected to channel 3 on disturbance function block A1RADR
L3
•
I
connected to channel 4 on disturbance function block A1RADR
N
•
U
connected to channel 5 on disturbance function block A1RADR
L1E
•
U
connected to channel 6 on disturbance function block A1RADR
L2E
•
U
connected to channel 7 on disturbance function block A1RADR
L3E
•
U
connected to channel 8 on disturbance function block A1RADR
EN
Channel number used for the remaining 32 analog signals are numbers in the
private range 64 to 95.
Binary signals, 128-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.
