Operation processing
• These functions output a value input to (s2) and (s3) according to a value input to (s1) in the same data type as (s2) and
(s3) from (d).
• When FALSE(=0) is input to (s1), these functions output an input value of (s2) from (d).
• When TRUE(=1) is input to (s1), these functions output an input value of (s3) from (d).
Ex.
The data type of (s2) and (s3) is the INT type ((s2) and (s3) of an argument correspond to the bit value of (s1) (0 or 1).)
• A value input to (s1) is the BOOL type data value.
• A data value of the BOOL, INT, DINT, WORD, DWORD, REAL, STRING, TIME, structure, or array type can be input to (s2)
and (s3).
