Processing details
■Operation processing
These functions output the mean value of the values input to the input variables IN[0] to IN[15] from the output variable OUT1.
OUT = (IN[0] + IN[1] + IN[2] + ... + IN[15])  NUM
IN[0] to IN[15]: Input value, OUT1: Output value, NUM: Input number
■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
(SD0)
3400H An invalid operation (such as division by zero) is performed.
3402H Input 1 to 16 are subnormal numbers or NaN (not a number).
3403H An overflow has occurred.
3405H The number of inputs is less than 1 or greater than 16.
