Bit 0 ... 3 can be written in Subindex 5 (abbreviation: SI5) by the master to
determine which type of message should be recorded (info, warning or error
messages) and whether the EMCY message should be sent to the master for
each diagnostic event.
Bit 4 indicates that the diagnostic history object is in "Acknowledge Mode". Before
a diagnostic message can be overwritten, it must be acknowledged. Bit 5 is set if
the ring memory is full. Bit 4 and 5 can only be read and not overwritten by the
master.
During the write operations to Subindex 5, bit 4 must always be written as 1; the
values for bit 5 are ignored (discarded).
If an incorrect value is written to SI5, then write access is denied with SDO abort
code 0x06090030.
The message slots are located in subindices 6 to 17. These slots represent a ring
memory.
Subindices 2 and 3 function like pointers to these ring memory slots and show
the value of the subindex of the newest logged message, SI2, and the value of
the last acknowledged message, SI3.
With each new recording and acknowledgement, the pointers are increased by
one slot until, after reaching the last slot (SI17), they return again to the first slot
(SI6) for the subsequent recording.
SI4 indicates whether unacknowledged diagnostic messages are present.

Function Description
Description
Number of subindices (= 17)
Number of message slots in this object (= 12)
Subindex of the newest logged diagnosis message
(SI must be in the range 6 ... 17)
Subindex of the last acknowledged message
TRUE = At least one unacknowledged message is
available
FALSE = No message or all messages have been
acknowledged
By spec, this equals the expression (SI2 != SI3)
Control Flags
Bit 0: 1 = enable EMCY sending
Bit 1: 1 = do not log info messages
Bit 2: 1 = do not log warning messages
Bit 3: 1 = do not log error messages
Bit 4: 1 = Acknowledge Mode (RO)
Bit 5: 1 = message buffer is full and a new message will
be discarded (RO)
