20.3.21 Subtractor details

20.3.21.1 Behaviour

The module subtracts the value of the Input 1 from the value of the Input 0 and outputs the re-
sult on the Output 0 (Input 0 - Input 1 = Output 0).
If necessary, incoming values are converted into the internal data type of the module before the
subtraction (see conversion table below). Thus, observe the selection of a correct internal data
type!
The comparison is dependent on the internal data type of the module and is executed in the fol-
lowing way:
Internal data type Procedure
