Read Data (Function Code 03)
Query
This function allows the master to obtain the measurement results from the meter.
Table 5-8 depicts reading slave device (address 17) Inline A real-time energy, Inline B real-
time energy, , Inline C real-time energy (these parameters are dword data type, each
parameter uses 2 addresses, each address uses 2 bytes). AcuRev 2000 Inline A real-time
energy address is 2500H, 2501H; Inline B real-time energy address is 2502H, 2503H; Inline C
real-time energy is 2504H, 2505H.
