ANY_TO_BOOLPLCopen motion icon

Operator - Converts the input into Boolean value.

Inputs

IN : ANY  Input value

Outputs

Q : BOOL  Value converted to Boolean

Remarks

For DINT, REAL and TIME input data types, the result is FALSE if the input is 0. The result is TRUE in all other cases. For STRING inputs, the output is TRUE if the input string is not empty, and FALSE if the string is empty. In FFLD language, the conversion is executed only if the input rung (EN) is TRUE. The output rung is the result of the conversion. In ILClosed"Instruction list" This is a low-level language and resembles assembly Language, the ANY_TO_BOOL function converts the current result.
