• MAX(_E)
Ex.
Data type is INT
• MIN(_E)
Ex.
Data type is 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.

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).
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).
