How many events are stored in diagnostics buffer (without archiving) in M580.

How can we help you today?

The number of messages displayed in the list is defined solely by the size of the available memory.
If the memory becomes insufficient:
the DIAG information flashes in the status bar,
the messages associated with faults that have disappeared and have been acknowledged (if they needed acknowledging) are deleted.

The Size of Diag / Diagnostic buffer is 4 KB.
