Date Code 20001006 MIRRORED BITS™ I-5
SEL-351 Instruction Manual
Mirrored Bits Receive bad pickup (1- 10000 sec) RBADPU= 60 ?
Use the RBADPU setting to determine how long a channel error must last before the relay element
RBADA is asserted. RBADA is deasserted when the channel error is corrected. RBADPU is
accurate to ±1 second.
Mirrored Bits Channel bad pickup (1- 10000 10E-6) CBADPU= 1000 ?
Use the CBADPU setting to determine the ratio of channel down time to the total channel time
before the relay element CBADA is asserted. The time used in the calculation are those that are
available in the COMM records. See the COMM command in the SEL-321 or SEL-351 manuals
for a description of the COMM records.
Mirrored Bits transmit identifier(1 - 4) TX_ID = 1 ?
Mirrored Bits receive identifier(1 - 4) RX_ID = 2 ?
Set the RX_ID of the local relay to match the TX_ID of the remote relay. For example, in the
three-terminal case, where Relay X transmits to Relay Y, Relay Y transmits to Relay Z, and Relay
Z transmits to Relay X:
TX_ID RX_ID
Relay X 1 3
Relay Y 2 1
Relay Z 3 2
Mirrored Bits receive default state (string of 1s, 0s or Xs)
87654321
RXDFLT=00000X11
?
Use the RXDFLT setting to determine the default state the MIRRORED BITS should use in place of
received data if an error condition is detected. The setting is a mask of 1s, 0s and/or Xs, for
RMB1A-RMB8A, where X represents the most recently received valid value.
