Detailed CGCM-DLR Unit Tag Descriptions
Appendix
E
•
GenRot_ABC_ACB
– This tag reports the rotation sequence of the
generator bus in 3-phase metering. In single phase metering, these bits
reflect the configuration value.
•
PhRotMatch
– This tag reports that the phase rotation between the two
busses to be synchronized matches, and is acceptable for synchronizing.
•
V_Match
- This tag reports that the voltage difference between the two
busses is within the configured acceptable range.
•
FreqMatch
- This tag reports that the frequency difference between the
two busses is within the configured acceptable range.
•
PhMatch
- This tag reports that the phase difference between the two
busses is within the configured acceptable range.
•
V_MatchErr
– This tag reports the percentage difference in voltage
between the two busses to be synchronized.
•
FreqMatchErr
– This tag reports the difference in frequency between the
two busses to be synchronized.
•
PhMatchErr
– This tag reports the phase difference between the two
busses to be synchronized.
•
CloseBusA_Brkr
– When this tag is 1, it indicates that synchronization
has reached a status where it is acceptable to close the breaker to Bus A.
•
CloseBusB_Brkr
– When this tag is 1, it indicates that synchronization
has reached a status where it is acceptable to close the breaker to Bus B.
•
Raise_V
– This tag indicates to the host Logix controller that the
synchronizing bus has a lower voltage level than that level of the reference
bus.
•
Lower_V –
This tag indicates to the host Logix controller that the
synchronizing bus has a lower voltage level than that level of the reference
bus.
•
Raise_Freq -
This tag indicates to the host Logix controller that the
synchronizing bus is producing voltage at a frequency lower than that
frequency of the reference bus.
•
Lower_Freq -
This tag indicates to the host Logix controller that the
synchronizing bus is producing voltage at a frequency higher than that
frequency of the reference bus
•
Raise_Ph -
This tag indicates to the host Logix controller that the
synchronizing bus is producing a voltage that is 0...180 degrees behind the
reference bus.
•
Lower_Ph -
This tag indicates to the host Logix controller that the
synchronizing bus is producing a voltage that is 0...180 degrees ahead of
the reference bus.
•
ActiveBusA_B
– This tag provides feedback as to which reference bus is
being monitored.
