Selecting Maximum/Minimum Value

MAX(_E), MIN(_E)
• MAX(_E): These functions output the maximum value of an input value.
• MIN(_E): These functions output the minimum value of an input value.

Processing details
■Operation processing
• MAX(_E)
These functions output the maximum value of the BOOL, INT, DINT, WORD, DWORD, DWORD, REAL, STRING, or TIME type data input to (s1) to (s28) in
the same data type as (s) from (d).
Ex.
Data type is INT
(s1) to (s28) (s1) to (s28)
1234 1234
INT INT
_IN1 _IN1
_IN2 _IN2
5678 5678
INT INT
• MIN(_E)
These functions output the minimum value of the BOOL, INT, DINT, WORD, DWORD, DWORD, REAL, STRING, or TIME type data input to (s1) to (s28) in
the same data type as (s) from (d).
Ex.
Data type is INT
(s1) to (s28) (s1) to (s28)
1234 1234
INT INT
_IN1 _IN1
_IN2 _IN2
5678 5678
INT INT
• A data value of the BOOL, INT, DINT, WORD, DWORD, REAL, STRING, or TIME type can be input to (s1) to (s28).
• The number of pins for (s) can be changed in the range of 2 to 28.
