● The measuring range center must be within the nominal range of the underlying
measuring range. It is specified in integers.
● The scalable measuring range is spanned symmetrically over the measuring range
center. Depending on the resolution, various value ranges result (
①, ②).
● The scalable measuring range is limited by underflow and overflow of the underlying
measuring range:
– It is clipped at the underflow when it falls below the limit.
– It is clipped at the overflow when it exceeds the limit (
③).
The following example illustrates the effect of scalable measuring ranges:
Scalable measuring range with 2 decimal places in hexadecimal S7 format
Scalable measuring range with 3 decimal places in hexadecimal S7 format
Scalable measuring range which is cut off at the overflow of the underlying measuring range (clipping)
