11.2.2 Input registers
Input registers are used to indicate the present values of the measured and calculated
electrical quantities. Each parameter is held in two consecutive 16 bit registers. The
following table details the 3X register address, and the values of the address bytes within
the message. A tick () in the column indicates that the parameter is valid for the
particular wiring system. Any parameter with a cross () will return the value Zero. Each
parameter is held in the 3X registers. Modbus Protocol Function Code 04 is used to access
all parameters.
For example, to request Amps 1 (current Phase
1)
Start address = 0006
No of registers = 0002
Amps 2 (current Phase
2) Start address = 0008
No of registers = 0002
Each request for data must be restricted to 40 parameters or less. Exceeding the 40
parameter limit will cause a Modbus Protocol exception code to be returned.
