Serial Port Communications and Commands
Command Explanations
To pulse
OUT101
for five seconds:
==> PUL OUT101 5 <Enter>
Are you sure (Y/N) ? Y <Enter>
==>
If the response to the
Are you sure (Y/N) ?
prompt is N or n , the command
is aborted.
The PUL command is supervised by the main board Breaker jumper (see
Table 2.5 and Table 2.6 ). If the Breaker is not in place (Breaker jumper =
OFF), the relay does not execute the PUL command and responds:
Aborted: No Breaker Jumper
The relay generates an event report if any of the
OUT101
through
OUT107
contacts are pulsed. The PULSE command is primarily used for testing
purposes.
Access Level 2
Commands
CON Command (Control Remote Bit)
The CON command is a two-step command that allows you to control Relay
Word bits RB1 through RB16 (see Rows 27 and 28 in Table 9.5 ). At the
Access Level 2 prompt, type CON , a space, and the number of the remote 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 10.8 ).
The following example shows the steps necessary to pulse Remote Bit 5
(RB5):
=>> CON 5 <Enter>
CONTROL RB5: PRB 5 <Enter>
=>>
You must enter the same remote bit number in both steps in the command. If
the bit numbers do not match, the relay responds
Invalid Command
.
See Remote Control Switches on page 7.10 for more information.
where:
x is the output name (e.g. OUT101 , OUT107 , ALARM ,
OUT211 —see Figure 7.27 and Figure 7.28 ).
y is the pulse duration (1–30) in seconds. If y is not
specified, the pulse duration defaults to one second.
