configure the name of the binary channel and modify it by writing the new name to
the Channel id text parameter of the corresponding binary channel.
Note that the Channel id text parameter is used in COMTRADE configuration files
as a channel identifier.
The recording always contains all binary channels of the disturbance recorder. If
one of the binary channels is disabled, the recorded state of the channel is
continuously FALSE and the state changes of the corresponding channel are not
recorded. The corresponding channel name for disabled binary channels in the
COMTRADE configuration file is Unused BI.
To enable or disable a binary channel of the disturbance recorder, the user can set
the Operation parameter of the corresponding binary channel to the values "on" or
"off".
The states of manual triggering and periodic triggering are not included in the
recording, but they create a state change to the Periodic triggering and Manual
triggering status parameters, which in turn create events.
The Recording started parameter can be used to control the indication LEDs of the
IED. The output of the Recording started parameter is TRUE due to the triggering
of the disturbance recorder, until all the data for the corresponding recording is
recorded.
The IP number of the IED and the content of the Bay name
parameter are both included in the COMTRADE configuration file
for identification purposes.

Application

The disturbance recorder is used for post-fault analysis and for verifying the correct
operation of protection IEDs and circuit breakers. It can record both analog and
binary signal information. The analog inputs are recorded as instantaneous values
and converted to primary peak value units when the IED converts the recordings to
the COMTRADE format.
COMTRADE is the general standard format used in storing
disturbance recordings.
The binary channels are sampled once per task execution of the disturbance
recorder. The task execution interval for the disturbance recorder is the same as for
the protection functions. During the COMTRADE conversion, the digital status
values are repeated so that the sampling frequencies of the analog and binary
channels correspond to each other. This is required by the COMTRADE standard.
