GE EPM 9650/9800 manual Type F63 Log Index, Type F64 Scaled Energy, Byte Hex

3.63: Type F63 Log Index

Length: 1 Register (2 bytes)

Range: 65,535 / 0

Unit: 1 Unit

This register contains a 2-byte MSB unsigned integer, which represents the First or Last Index for a given Log. First Indexes represent the Index of the First (Oldest) record in a log. Last Indexes represent the Index of the Last (Newest) record in a log. The value of 0x0FFFF for the Last Index indicates that the log is empty.

3.64: Type F64 Scaled Energy

Length: 2 Registers (4 bytes)

Range: 99 / 0 through 999,999,999 / 0 (variable, 2-9 digits)

Unit: 10-7through 106 units (variable)

This register contains an 4-byte signed integer. The range and resolution of a given reading is controlled by programmable Energy Scale Settings, which govern both the range of the reading (from 2 to 9 digits) and the units of the reading (from 7 decimal places of Wh (10-7) to no decimal places of MWh (106). Refer to Type F65 for a description of the Scaled Energy Programmable Setting (Device Profile > Revenue & Energy Settings > Energy Scaling).

Example:

Registers 06912-06913, Total VAh (Quadrant 1+2+3+4) Scaled Primary, might contain the following data:

Address	06912	06913
Value	075BH	CD15H
4-byte Hex		075HCD15H
Decimal		123,456,789

If the Programmable Settings indicated 5 decimal places of WH, then the interpreted value would be 1,234.56789 Wh.

If the Programmable Settings indicated 0 decimal places of MWh, then the interpreted value would be 123,456,789 MWh.
