Operation error
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
Operation error
• An operation error occurs in the following cases.
Error Description
code
4100 The value to be input to (s2) is 0. (Division by 0)
Program example
■DIV_E
The program which performs division ((s1)  (s2)) on double word (signed) type data input to (s1) and (s2), and outputs the
quotient of the operation result from (d) in the same data type as that of (s1) and (s2).
