Example 5: Getting Data From a Non-SEL IED
Set the SEL-2032,
Step by Step
Step 1. Use SET P 12 to configure Port 12 as an “Other IED” port with
the DGH 1000 communication parameters. Your settings
should look like those in
Table 3.9 .
Step 2. Set the SEL-2032 with the SET A 12 command to collect data
from the DGH 1000 every 30 seconds. Your settings should
look like those in
Table 3.10 .

MSG_CNT 1 Set MSG_CNT=1 to add a new message trigger
and message.
ISSUE1 P00:00:30.0 Periodically trigger MESG1 every 30 seconds.
MESG1 “$1RD\00D” Send the command $1RD to
request temperature data from the
DGH 1000. The carriage return, \00D, is
required to complete the command sequence.
PARSE1 2 Select the ASCII_FLOAT
parsing method because you know
the temperature is in floating-point format.
NUM1 1 Accept one item because you know
only one number is returned from the DGH 1000.
DELAY1 ON Since we know only one data item is coming
in, we could set DELAY1 to OFF. If we wanted
to collect data more often than every 5 seconds,
we would need to set it OFF to avoid the idle time
check. Since we are only collecting the data every
30 seconds, the value of the setting does not
matter.
