STRING (decimal format right-justified) into unsigned INTEGER

STRING_TO_UINT_STEPSAVER converts a right-justifed decimal number in a string into a value of the data type Unsigned INTEGER.

Parameters

Input

Unnamed input (STRING): Input data type

Output

Unnamed output (UINT): Conversion result

Remarks

The basic instruction F76_A2BIN with approx. 7 steps is used. The PLC issues an operation error especially if anything other than acceptable characters are used (see the following table "Acceptable characters").

Acceptable Format: '[Space][Sign][Decimal number]', e.g. '123456'
