Q
Digital Output Snapshot Log: The Digital Output Snapshot Log will fill to the total allocated
memory. The number of records possible in the Digital Output Log is the total memory allocated
divided by the record size (size of a Digital Output Snapshot).
Profile Information is in the Programmable Settings Block.
Q
Digital Output Snapshot Record Size: (45463)
This Register is an enumeration for the size of a record in the Digital Output Snapshot Log. The
valid values are:
0x00000 = 32 byte records
0x00001 = 64 byte records
0x00002 = 128 byte records
0x00003 = 256 byte records
0x00004 = 16 byte records
Q
Digital Output Snapshot Data Pointers: (45205-45332)
These Registers indicate which information to include in a record in the Digital Output Snapshot
Log. Each Data Pointer has the following 4 (four) byte structure:
Size Format Description
2 byte unsigned int Line Number
1 byte unsigned char Point number
1 byte unsigned char Reserved
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.
A Point Number is an index into the Communication Table.
Example: Point Number 1 is for the second entry in a Line. Line Number 11, Point Number 1 is
the second in the twelfth line, 0.1 second V
BN
. Data Pointers with Point Numbers greater than the
number of points for the line are ignored.
