20 SELECTION FUNCTIONS
20.4 Multiplexer
20.4 Multiplexer
MUX(_E)
These functions output one of multiple input values.
*1 The input variable "s" can be changed in the range of 2 to 28.

■Descriptions, types, and data types
Processing details
■Operation processing
• These functions output one of values input to (s1) to (s28) according to the input value of (n) in the same data type as (s)
from (d).
• When 0 is input to (n), these functions output a value input to (s1) from (d).
• When (n)-1 is input to (n), these functions output a value input to (sn) from (d).
Ex.
Data type is INT
• When a value input to (n) is outside the pin number range for (s), these functions output an indefinite value from (d). (An
operation error does not occur. "MUX_E" outputs "FALSE" from ENO).
• A value input to (n) is the INT type data value and within the range from 0 to 27. (The value must be in the pin number
range for (s).)
• A data value of the BOOL, INT, DINT, WORD, DWORD, REAL, STRING, TIME, structure, or array type can be input to (s).
