11.2.1.7 Subindexes 6–69: Diagnosis Message (Write-Protected)
Depending on subindex 1, the EtherCAT slave can store up to 64 diagnostic messages.
In the process, the first message is stored in subindex 6, the second in subindex 7 etc.
When the buffer is full, the EtherCAT slave overwrites subindex 6 etc., so the last diag-
nostic messages are accessible to the EtherCAT master. The exact number of them is in-
dicated by subindex 1.
