The four tables in this appendix contain an abbreviated listing of
meter registers. For registers defined in bits, the rightmost bit is
referred to as bit 00. Figure A–1 shows how bits are organized in a
register.

The meter registers can be used with MODBUS or JBUS protocols.
Although the MODBUS protocol uses a zero-based register
addressing convention and JBUS protocol uses a one-based register
addressing convention, the meter automatically compensates for the
MODBUS offset of one. Regard all registers as holding registers
where a 30,000 or 40,000 offset can be used. For example, Current
Phase A will reside in register 31,100 or 41,100 instead of 1,100 as
listed in Table A–3 on page 122.
Floating-point registers are also available. See Table A–7
on page 181 for an abbreviated list of floating-point registers. To
enable floating-point registers, see "Enabling Floating-point
Registers" on page 218.
