IEC operator for conversions from type BOOL to any other type.
BOOL_TO_<data type>
The conversion results for number types and for string types depend on the state of the operand:
|
Operand State |
Result for Number Types |
Result for String Types |
|---|---|---|
|
TRUE |
1 |
TRUE |
|
FALSE |
0 |
FALSE |
