For diagnostic reasons, the Irinos system gathers all events reported by the local firmware in a non-volatile event memory. Events can be visualized via the built-in web server, or alternatively upon request within the Irinos Tool.
Diagnostic events are displayed for the entire system, i.e. event data is gathered box by box and finally displayed as a system-wide view. Grouping and sorting of events is supported to facilitate easy cross-box event analysis.

A diagnostic memory entry has the followings attributes:
| Box-Nbr | Number of the Irinos-Box: the event occurred at the Irinos-Box with this address. | 
| Nbr | Event number (per Box) | 
| Event Type | Event type (numerical value) | 
| Event description | Event type as text | 
| Add. Info | Additional information for the cause of the event | 
| Absolut Time | Date/Time the event occurred (only available, if the absolute time has been set before). | 
| Internal Time | Internal system time (ILink-Time, [µs]) | 
| Firmware version | Firmware version at the time the event occurred. | 
| Debug Info | Further information for manufacturer support. | 
Newly-created events can be obtained by the update buttons.
If required, the entire event data can be saved into a CSV file by pressing the “Save CSV file” button. After pressing the button a file selection dialogue is displayed. File name and location can be specified by the user.
