There may be up to 255 records in the extended report. To limit the number of COMM records
displayed in the report to the 10 most recent records, type COMM 10 L <ENTER>. To select
lines 10 through 20 of the COMM records for display in the report, type COMM 10 20 L
<ENTER>. To reverse the order of the COMM records in the report, supply a range of row
numbers, with the larger number first, i.e., COMM 40 10 L <ENTER>. To display all the
COMM records that started on a particular day, supply that date as a parameter, i.e., COMM
2/8/98 L <ENTER>. To display all the COMM records that started between a range of dates,
supply both dates as parameters, i.e., COMM 2/21/98 2/7/98 L <ENTER>. Reversing the order
of the dates will reverse the order of the records in the report. To receive a summary report for a
subset of the records, use one of the above methods while omitting the L parameter.
Events occurring while loop-back mode is enabled will have an L appended to the record in the
report.
To clear the COMM records, type COMM C <ENTER>. The prompting message “Are you sure
(Y/N) ?” is displayed. Typing N <ENTER> aborts the clearing operation with the message
“Canceled.”
CONTROL n (SEL-321-1 Relay Only)
The CONTROL command is a two-step, Access Level 2 command that allows you to control
Relay Word bits RB1 through RB16. At the Access Level 2 prompt, type CONTROL, a space,
and the number of the bit you wish to control (1-16). The relay responds by repeating your
command followed by a colon. At the colon, type the CONTROL subcommand you wish to
perform (see Table 3.3).
The following example shows the steps necessary to pulse Remote Bit 5 (RB5) for three seconds.
