(Process)
These functions write a value to the specified bit of a word label.

Processing details
■Operation processing
• These functions write a BOOL data type value specified by (s) to the (n)th bit of (d).
■Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
