Operation processing
• These functions output one of the values input to (s1) to (s28), in the same data type as (s), from (d) according to the value
input to (n).
• If the (n) input value is 0, the value input to (s1) is output from (d).
• If the (n) input value is (n)-1, the value input to (sn) is output from (d).
Ex.
Data type: INT
• If a value outside the range of the number of pins in (s) is input to (n), an undefined value is output from (d). (No operation
error occurs. When MUX_E is used, ENO outputs FALSE.)
• Input an INT data type value to (n) within the range of 0 to 27, provided that it is within the range of the number of pins in (s).
• Input a BOOL, INT, DINT, WORD, DWORD, REAL, LREAL, STRING, TIME, structure, or array data type value to (s).
