Exceptions are reactions to prohibited states of the program execution. The exception settings is defined in the Controller properties.
| stop when exception\\ | description |
| 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:
| Inputs | Outputs |
| in = 0 | -Infinity |
| in < 0 | NaN |
| Inputs | Outputs |
| in = 0 | -Infinity |
| in < 0 | NaN |
| Inputs | Outputs |
| in < -1 | NaN |
| in > 1 | NaN |
| Inputs | Outputs |
| in < -1 | NaN |
| in > 1 | NaN |
| Inputs | Outputs |
| in = -1 | -Infinity |
| in = 1 | +Infinity |
| in < -1 | NaN |
| in > 1 | NaN |
EXP,EXP10, and %%**%% - powers
| Inputs | Outputs |
| “in” is too large\\ | +Infinity/-Infinity |
| Inputs | Outputs |
| 0/0 | NaN |
| X/0 where X<0 | -Infinity |
| X/0 where X>0 | +Infinity |
| X/0 where both inputs are ANY_INT | 0 |
| Inputs | Outputs |
| X/0 | result=0 eno=false |
| Inputs | Outputs |
| X mod 0 where inputs are real | NaN |
| X mod 0 where inputs are ANY_INT | 0 |
| Inputs | Outputs |
| X mod 0 | result=0 eno=false |
Invalid address or range always returns an area with zeros.
Invalid address or range results in no writing.
Invalid pointer or reference results in no call.
Read and write into memory
Reading or writing beyond the address space results in no action.
