15.9 Description of the "Digitalisation" modules
In the "Digitalisation" selection area, available modules for digitalisation are displayed . The modules
convert numerical values at the inputs into comparable binary expressions .
The "Digitalisation" modules can process individual signals or vectors at the inputs:
►
No combination of single values and vectors .
►
Use vectors of the same size .
►
Use single values only .
The "Digitalisation" selection area contains the following modules:

The signal at input "in1" is compared with t1he threshold values "in2" and
"in3" .
"in2" < "in3":
●
if "in1" < "in2", then "out1" = "0"
●
if "in1" > "in3", then "out1" = "1"
●
if "in2"
≤ "in1" ≤ "in3", then "out1"
remains unchanged
