Exceptions are reactions to prohibited states of the program execution. The exception settings is defined in the Controller properties.
| TRUE | If there is an exception, the program execution stops. In the System status tab it is displayed which exception appeared, and where. |
| FALSE | If there is an exception, the program keeps on running. The block output diplays the status according to the exception table:
NaN - the value is not a number
- Infinity
+ Infinity |
Exception catched in the System status:
| in = -1 | -Infinity |
| in = 1 | +Infinity |
| in < -1 | NaN |
| in > 1 | NaN |
"in" is too large
| +Infinity/-Infinity |
| 0/0 | NaN |
| X/0 where X<0 | -Infinity |
| X/0 where X>0 | +Infinity |
| X/0 where both inputs are ANY_INT | 0 |
| X mod 0 where inputs are real | NaN |
| X mod 0 where inputs are ANY_INT | 0 |
| X mod 0 | result=0 eno=false |
