701 Motor Protection Relay Date Code 20010719
SEL-2020/2030 & SEL-701PC Compatibility Features
CEVENT Command
D.26
CEVENT Command
Display event report in compressed ASCII format by sending:
CEV n
where:
n event number (1–n), defaults to 1.
The relay responds to the CEV command with the nth event report as shown
below. The relay replaces the items in italics with the actual relay data.
The SEL-701 Relay sends:

(4 or 16).
"SAM/CYC_D" is the number of digital data samples per cycle
(4 or 16).
"NUM_OF_CYC" is the number of cycles of data in the event
report.
"TYPE" is the event type.
