PART 3

 

Modbus Protocol

   

 

Input registers are used to indicate the present values of the measured and calculated electrical quantities. 
Each parameter is held in two consecutive16 bit register. The following table details the 3X register address, 
and the values of the address bytes within the message. A (*) in the column indicates that the parameter 
is valid for the particular wiring system. Any parameter with a cross(X) 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        Start address=0006 
                                                                          No. of registers =0002 
                                                    Amps 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.
