6-6
32nd Limit's Value 1 Comparison. Abit value of 1 means that the Comparison is exceeded: less
than or equal to Value 1 for a below limit, greater than Value 1 for an above limit. Abit value of
0 means that the Comparison is not exceeded: greater than Value 1 for a below limit, less than or
equal to Value 1 for an above limit.
•The next four bytes are the same bitmap as above, but for the current state of the Value 2
Comparisons of the Limits.
•The next four bytes are a bitmap for the delta of the Value 1 Comparisons of the Limits. The
order of the bits is the same as above. Abit value of 1 means that the state of the Value 1
Comparison changed since the last Alarm occurred; a bit value of 0 means that the state of the
Value 1 Comparison did not change since the last Alarm.
•The next four bytes are the same bitmap as above, but for the delta of the Value 2 Comparisons
of the limits.
•The next four bytes are a bitmap for the current state of the Combination of the Limits. The
first bit(the most significant bit of the first byte) is the current state of the 1st Limit’s
Combination of the Value 1 Comparison and the Value 2 Comparison. The last bit (the least
significant bit of the fourth byte) is the current state of the 32nd Limit’s Combination of the
Value 1 Comparison and the Value 2 comparison. Abit value of 1 means that the Combination
is true, a bit value of 0 means that the Combination is false.
•The last 4 bytes are the same bitmap as above, but for the delta of the Combination of the
Limits.

QLimit Data Pointers: (45077-45204)
These Registers indicate which values are being monitored by limits. Each Data Pointer has the
following 8 (eight) byte structure:
Size Format Description
2 byte unsigned int Line Number
1 byte unsigned char Point number
1 byte unsigned char Limit Mode
2 byte unsigned int Comparison 1 Value
2 byte unsigned int Comparison 2 Value
ALine Number is an index into the Communication Table.
Example: Line Number 11 is for the 12th line in the Communication Table, 0.1 second Phase-to-
Neutral Voltages. Data Pointers with Line Numbers greater than the number of lines in the table are
ignored.
