The input registers from the Sine wave filter are mapped to Modbus register address 40000, see
Table 20 through Table 22 for definitions of the input register maps. The output registers are
mapped to Modbus register address 40500, see Table 20 through Table 22. All input and output
registers are two bytes in size and formatted as 16-bit signed integers.
Note: All parameters with an asterisk (*) in the description will require the Tech level access codes
