ST Operator |

Description |
The output is the result of Input 1 divided by Input 2. On a Function Block Diagram, Input 1 is the top input and Input 2 is the bottom input. |
|
Arguments |
Input 1 {ANY_NUM} Input 2 {ANY_NUM} For more information on the data types for the inputs and outputs, see Data Type Hierarchy. |
|
Returns |
Output {Same data type as Input 1} The value of Input 1 divided by Input 2. The type of output is dependent on the inputs. |
NOTE: For integer inputs, the output is the same as Input 1 except that the fractional part of the value is discarded.
Example:
Function Block Diagram - DIV:
Input 1 is 10 (the top input) and Input 2 is 5 (the bottom input). The output is 5 as 10 divided by 5 is
ST Program - DIV:
The DIV function is used to provide the result of Input 1 divided by Input 2.
- Output := Input 1 / Input 2;
Where Output, Input 1 and Input 2 are defined as variables earlier in the ST program. In this case, let's assume Input 1 is 60 and Input 2 is 10. The DIV function returns 6 as 60/10=6.
Alternatively, the same calculation can be made by using the following syntax:
- Output := DIV (Input 1, Input 2);
