2 Instruction Descriptions
The following example for the STRING_TO_DINT instruction is for when In is '123456789'.
LD
'123456789'
STRING data
In
'123456789'
The valid range of In depends on the data type of Out as shown below:
Data type of Out
USINT
UINT
UDINT
ULINT
SINT
INT
DINT
LINT
* Any blank characters (' ') at the beginning of the text string, any zeros at the beginning of the text string, and any
underbars ('_') in the text string are not included in the number of bytes.
Additional Information
• To convert a text string to a hexadecimal number, use a STRING_TO_** (Text String-to-Bit String
Conversion Group) instruction (page 2-301).
• To convert an integer to a text string, use a **_TO_STRING (Integer-to-Text String Conversion
Group) instruction (page 2-283).
Precautions for Correct Use
• Always use the correct instruction name for the data type of Out.
• If the value of In is '−0', the value of Out is 0.
• An error occurs in the following cases. ENO will be FALSE, and Out will not change.
• The text string in In does not express a number.
• The conversion result exceeds the valid range of the data type of Out.
