Instruction Manual
SEL-421-4, -5 Relay Command Summary
Command
a, b
Description
2ACCESS Go to Access Level 2 (complete relay monitoring and control)
89CLOSE Close disconnect switch n (n = 1–10)
89OPEN Open disconnect switch n (n = 1–10)
AACCESS Go to Access Level A (automation configuration)
ACCESS Go to Access Level 1 (monitor relay)
BACCESS Go to Access Level B (monitor relay and control circuit breakers)
BNAME List ASCII names of Fast Meter status bits
BREAKER n Display the circuit breaker report and breaker history; preload and reset breaker monitor data (n = 1 is BK1; n = 2 is
BK2)
CASCII Generate the Compressed ASCII response configuration message
CBREAKER Display Compressed ASCII breaker status report
CEVENT Display Compressed ASCII event report
CFG CTNOM i For TiDL relays, configure the nominal CT input value i to 1 or 5
CFG NFREQ f In TiDL relays, set the nominal frequency, f (50 or 60)
CHISTORY Display Compressed ASCII history report
CLOSE n Close the circuit breaker (n = 1 is BK1; n = 2 is BK2)
COM c Display relay-to-relay M
IRRORED BITS communications or remote synchrophasor data (c = A is channel A; c = B is
channel B; c = M is either enabled single channel)
COM RTC Display statistics for synchrophasor client channels
COM PTP Display a report on PTP data sets and statistics
CONTROL nn Set, clear, or pulse an internal remote bit (nn is the remote bit number from 01–32)
COPY m n Copy settings between instances in the same class (m and n are instance numbers; for example: m = 1 is Group 1;
n = 2 is Group 2)
CPR Display Compressed ASCII signal profiling report

GROUP Display the active group number or select the active group
HELP List and describe available commands at each access level
HISTORY View event summaries/histories; clear event summary data
ID Display the firmware id, user id, device code, part number, and configuration information
LOOPBACK Connect M
IRRORED BITS data from transmit to receive on the same port
