IPScom Setup Oscillograph Recorder

NOTE
: Communication must be established with
the target relay for this procedure. When
not connected to the relay the Save se-
lection does not save the Oscillograph
Recorder settings to an open file.
To setup the Oscillograph Recorder perform the
following:
1. From the IPScom Main Screen menu
select
Relay/Oscillograph/Setup
.
IPScom will display the Setup Oscillo -
graph Recorder dialog screen (Figures
4-12 and 4-13).
2. Select the
Number of Partitions
.
The recorder’s memory may be parti-
tioned into 1 to 24 partitions. The relay
Oscillograph Recorder memory buffer is
fixed and contains room for a finite num -
ber of cycles of recorded data. Consider
Table 4-2 when determining the number
of Oscillograph records, The number of
cycles of recorded data is directly related
to the number of records selected.
3. Select the desired
Trigger Inputs
and
Trigger Outputs .
The recorder can be triggered remotely
through serial communications using
IPScom, or automatically using pro-
grammed status inputs or outputs.
4. Select the
Post Trigger Delay
.
A post-trigger delay of 5% to 95% must
be specified. After triggering, the re-
corder 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.
5. Select Save , IPScom will display a save
to device Confirmation Screen (Figure
4-2).
