Each Irinos box has an integrated, non-volatile diagnostic memory in which the events that have occurred are stored (provided that saving is activated for the respective event). It can be read out via the webserver as well as via the Irinos-Tool.

The diagnostic memory is therefore an important tool for tracing occurring problems and limiting their causes. This is especially true if an error occurs sporadically.

At least 32 entries per Irinos box can be stored in the diagnostic memory. As soon as it is full, the oldest entries are automatically deleted, creating space for new entries.

 

In addition to the actual diagnosis event, a diagnosis entry contains some additional information that can help you find the cause. These include the system time (EC-Link time) and the absolute time.

The EC-Link time corresponds to the time in µs since the Irinos system was started. It is uniform on all Irinos boxes of a system.

The absolute time contains the date and time of the diagnostic entry. Since the Irinos system does not contain a real-time clock, the absolute time is always 0 when the system is started. It should then be written from the PC. This is done via the software interface. Each subsequent diagnostic entry is then provided with the absolute time.

 

After switching on, the diagnostic entry "System (1)" with the help text "System started" is stored in each Irinos box. This makes it possible to see whether an event occurred before or after the Irinos system was last switched on.
