These instructions convert a text string, In, to an integer.
Basically, the text string in In must consist only of numbers 0 to 9. The following exceptions are possi-
ble.
• If the first character in In is a single minus sign (−) or a single plus sign (+), it is processed as the sign.
• Any blank characters at the beginning of In are ignored.
• Any blank characters between an initial minus sign (−) or plus sign (+) and a number are ignored.
• Any single underbars ('_') at any location are ignored.
• An error occurs if there are two or more consecutive underbars ('_') at any location.
• An error occurs if there are any underbars ('_') at the beginning or end.
• An error occurs if there are any underbars ('_') between the minus signs ('−') or plus sign ('+') and the
number at the beginning.
The name of the instruction is determined by the data type of conversion result Out. For example, if Out
is the DINT data type, the instruction is STRING_TO_DINT.
