Oscillograph Recorder Data
The Oscillograph Recorder provides comprehensive
data recording (voltage, current, and status input/
output signals) for all monitored waveforms (at
16 samples per cycle). Oscillograph data can be
downloaded using the communications ports to
any IBM compatible personal computer running the
S-3400 IPScom
®
Communications Software. Once
downloaded, the waveform data can be examined
and printed using the optional M-3801D IPSplot
®
PLUS Oscillograph Data Analysis Software.
▲ CAUTION:
Oscillograph records are not retained
if power to the relay is interrupted.
The general information required to complete the
input data of this section includes:
•
Recorder Partitions
: When untriggered,
the recorder continuously records waveform
data, keeping the data in a buffer memory.
The recorder's memory may be partitioned
into 1 to 16 partitions.
When triggered, the time stamp is recorded,
and the recorder continues recording for a
user-defined period. The snapshot of the
waveform is stored in memory for later
retrieval using IPScom Communications
Software. The
OSC TRIG
LED on the front
panel will indicate a recorder operation
(data is available for downloading).
•
Trigger Inputs and Outputs
: The recorder
can be triggered remotely through serial
communications using IPScom, or
automatically using programmed status
inputs or outputs.
•
Post-Trigger Delay
: A post-trigger delay
of 5% to 95% must be specified. After
triggering, the recorder will continue to
store data for the programmed portion of
the total record before re-arming for the
next record. For example, a setting of 80%
will result in a record with 20% pre-trigger
data, and 80% post-trigger data.

NOTE:
Oscillograph recorder settings are not
considered part of the Setpoint Profile.
Recorder settings are common to all
profiles.
