Operation Error
An operation error occurs in the following case.
• The value to be input to is 0. (Division by 0) (Error code: 4100)
Program Example
The program which performs division ( ÷ ) on double word (signed) type data input to and
, and outputs the quotient of the operation result from in the same data type as that of .
(a) Function without EN/ENO (DIV)
[Structured ladder]
[ST]
g_dint3:= g_dint1/g_dint2;
(b) Function with EN/ENO (DIV_E)
[Structured ladder]
[ST]
g_bool3 := DIV_E(g_bool1, g_dint1, g_dint2, g_dint3);
