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.
*1 The input variable "s" can be changed in the range of 2 to 28.

• 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.

d:=MAX(s1,s2);
d:=MIN(s1,s2);
[With EN/ENO]
d:=MAX_E(EN,ENO,s1,s2);
d:=MIN_E(EN,ENO,s1,s2);
Argument Description Type Data type
EN Execution condition (TRUE: Execution, FALSE: Stop) Input variable BOOL
s1(IN1) to s28(IN28) Input Input variable ANY_ELEMENTARY
ENO Output status (TRUE: Normal, FALSE: Abnormal) Output variable BOOL
d(MAX(_E) / MIN(_E)) Output Output variable ANY_ELEMENTARY
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).
