Key Takeaways
- Wide character string supporting Unicode for international character sets.
- Advanced-level topic in Data Types & Variables
- Related to: STRING, CHAR, BOOL
Detailed Definition
Wide character string supporting Unicode for international character sets. This term is essential for understanding data types in industrial automation and PLC programming.
WSTRING is part of the type system defined by IEC 61131-3, the international standard for PLC programming languages. Wide character string supporting Unicode for international character sets.
The right type choice depends on the value range you actually need, the precision tolerated, the memory budget on your controller, and how the data will be consumed downstream. Choosing too small a type causes overflow bugs that are hard to detect on the bench; choosing too large wastes memory and bandwidth that adds up across thousands of variables on a large project.
For commissioning engineers, the most reliable diagnostic with WSTRING is to inspect the variable in the IDE's online watch table while toggling related inputs — type-mismatch bugs are caught faster by direct observation than by reading code.
