5.1.36 STR_TO_BOOL(_E)
Outline
This function converts string data into bit data, and outputs the data obtained by conversion.
1. Format
*1.
Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function converts string data stored in a device specified in
into bit data, and outputs the data
obtained by conversion to a device specified in
.
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling character string data in structured programs, you cannot specify 16-bit devices directly,
2) When handling character string data in structured programs, you cannot specify 16-bit devices directly,
different from simple projects. Use labels when handling string data.
Use global labels when specifying labels.
Use global labels when specifying labels.
