Response with different data widths and/or different signs
If the selected data format is insufficient for successful scaling, the value is automatically set
to the maximum or minimum value, even though the original value would require a higher or
lower value. In this case the target value of the scaling is limited and remains in this
constraint until the maximum/minimum value is undershot or exceeded again.
Example:
In the example, a signed value from the KNX bus (> 8 bits data width) is scaled to an
unsigned 8-bit value in the LOGO! 8. The offset (b) in this example is "0" and the gradient (a)
is "1".

Response with floating-point values
In the case of floating-point values, the interpolation points on the KNX side are specified
with decimal places and the values transferred to the LOGO! are rounded off if necessary by
the CMK2000.
Response with vertically superimposed interpolation points
User error which cannot be intercepted by the ETS. The maximum value is transferred.
