Processing details
■Operation processing
These functions output the maximum value of the values input to the input variables IN[0] to IN[15] from the output variable
OUT1. They set the bit corresponding to the input value selected as the maximum value from the input variables IN[0] to
IN[NUM] specified by the input number NUM to 1 and output the bit from the output variable OUT2. (When multiple maximum
values are input, they set all the corresponding bits to 1 and output the bits from the output variable OUT2.)
Ex.
When the input values of the input variables IN[0] and IN[2] are the maximum values

■Operation result
• Function block without EN/ENO
Operation result
No operation error
Operation error
• Function block with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (operation execution)
FALSE (operation stop)
*1 If the value FALSE is output from ENO, the output data from this function block will be undefined. Create a program so that the
undefined value will not be used in operations.
Operation error
Error code Description
