Processing details
■Operation processing
These functions output the intermediate value of the values input to the input variables IN[0] to IN[15] from the output variable
OUT1.
• They rearrange the input values in order from the smallest one to the largest one, and output the intermediate value of the
input values.
1, 3, 4, 5, 1  1, 1, 3, 4, 5
[Example]
In this case, 3 is output as the intermediate value.
• If the number of inputs is even, they output the smaller one from the output variable OUT1.
1, 3, 4, 5, 1, 4  1, 1, 3, 4, 4, 5
[Example]
In this case, 3 is output as the intermediate value.
They set the bit corresponding to the input value selected as the intermediate 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 intermediate values
are input, they set all the corresponding bits to 1 and output the bits from the output variable OUT2.)

■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.
