Block Point List
List all addressable points. Points that do not exist (for example, because an option is not installed)
shall be omitted from the table.

The scaling information for each point specifies how data transmitted in integer variations (16 bit and
32 bit) is converted to engineering units when received by the Master (i.e. scaled according to the
equation: scaled value = multiplier * raw + offset). Scaling is not applied to Floating point variations
since they are already transmitted in engineering units.
Resolution is the smallest change that may be detected in the value due to quantization errors and is
given in the units shown in the previous column. This parameter does not represent the accuracy of the
measurement.
