How does the scaling configuration in Modbus configuration work?
The scaling calculation is based on differentiation. Example:
The frequency is internally (in the relay) stored as an integer value which also holds three decimal places, that is, 50.000 Hz is represented as 50000. This is a value too large to be represented with 16 bits (signed integer). Frequency is by default scaled with the points: (x1, y1) = (0, 0) and (x2, y2) = (10, 1) enabling it to be sent over Modbus.
