Limit's Value 1 Comparison. A bit 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. A bit 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. A bit 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 1

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 32

Limit’s Combination of the
Value 1 Comparison and the Value 2 comparison. A bit 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

Limit 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
A Line 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.
