Job Done Examples
Example 4: Collect Unsolicited Write (Synchrophasor) Data
Step 2. Configure the SEL-311C serial port settings; this example uses
port 2.
NOTE: Port 2 on the SEL-311C is the
only serial port that accepts IRIG. If
the SEL-2032 will be used to
synchronize the SEL-311C to the IRIG
signal, Port 2 of the SEL-311C must be
used.
➢ Enter Access Level 2 on the SEL-311C and issue the
command SET P 2 to configure serial Port 2.
➢ Configure the SEL-311C serial port as in Table 3.7.
Note that the maximum SPEED for an SEL IED (non-
master) serial port connected to an SEL-2032 is 19200.
➢ Enter Y to save the port configuration changes at the
final prompt.
Step 3. Connect the SEL-311C to an SEL-2032 port; this example uses
Port 3.
Use the SEL C273A cable that handles both communication
and IRIG-B.
➢ Connect the end labeled SEL-300/500 series w/IRIG to
Port 2 on the SEL-311C.
➢ Connect the other end of the cable to Port 3 on the SEL-
2032.
Step 4. Enter Access Level 2 on the SEL-2032 and issue the command
SET P 3 to configure Port 3.
The SEL-2032 prompts for the type of device connected to the
port.
➢ Enter S for SEL IED, Y to auto-configure the port, and
press the <Enter> key to confirm the configuration
prompts.
The SEL-2032 establishes communication with the
relay; determines the type of relay, relay ID, and
communication baud rate; and determines if the relay is
capable of Fast Meter, Fast Operate, and Fast Messages.
This process can take a few minutes depending on the
baud rate.
➢ Enter Y to save port configuration changes at the final
prompt.
