➀ These registers can be used with POWERLOGIC, Modbus, or Jbus protocols. Although POWERLOGIC
and Jbus protocols use a zero-based register addressing convention and Modbus uses a one-based
register addressing convention, the power meter, when configured for Modbus communications,
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 (e.g., Current, Phase A = 31,003 or 41,003).
➁ PM-650 only.
