SIMPRO-PC Compatibility Features
SIMPRO-100
200 PRIM-2400C
If the history buffer is empty, the relay responds:
If the relay does not support voltage
measurement, the voltage and power labels are
replaced with “*”.
If the relay is not equipped with internal or
external RTD inputs, the RTD labels are replaced
with: “*”. If Fahrenheit is the designated
temperature scale, the temperature designator
(C) is replaced with (F).
D.8 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 SIMPRO-100 Relay sends:
where:
• "xxxx" are the data values corresponding
to the line labels.
• "yyyy" is the 4-byte hex ASCII
representation of the checksum.
• "FREQ" is the power system frequency at
the trigger instant.
• "SAM/CYC_A" is the number of analog
data samples per cycle (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.
• "TRIG" refers to the trigger record.
• "IA", "IB", "IC", "IN", "IG", "3I2" are the
summary currents.
• "VAB", "VBC", and "VCA" are replaced by
“VA”, “VB”, and “VC” in the event body
when phase-neutral potentials are
applied. They are replaced by “*” when
voltages are not included.
• "TRIG" refers to the trigger record.
• "z" is “>” for the trigger row, “*” for the fault
current row and empty for all others. If the
trigger row and fault current row are the
same, both characters are included
(e.g., “>*”).
• "HEX-ASCII Relay Word" is the hex ASCII
format of the Relay Word. The first
element in the Relay Word is the most
significant bit in the first character.
