SEL-2020 Instruction Manual
SET THE SEL-2020, STEP-BY-STEP
Set all SEL-2020 ports that you want to collect event reports using the following steps:
1. Use the SET U command to enable the pre-defined user-defined command 20EVENT on
Port 1. 20EVENT is a pre-defined string for user-defined commands that asserts the
corresponding CMD bit when the SEL-2020 receives a summary event report. See Section
8: Message Strings for a list of pre-defined strings.
You should see the following screen:
*>>SET U 1<ENTER>
SET U 1<ENTER>SET U 1<ENTER>
SET U 1<ENTER>

Notes:
Set CMD_CNT to 1 to open one user-defined command setting. Because this port was
configured as an SEL IED port in the previous examples, only four commands can be set.
Master ports have eight (8) command settings available.
Set CMD1=20EVENT. This settings tells the SEL-2020 to look for summary event
reports. When it receives a summary report, the CMD1 element on this port is asserted.
