4.5.4 Diagnosis History
The diagnostic history of the TwinSAFE devices that support this function is implemented in accordance with
the

TwinCAT.
Both the control entries and the history itself can be found in the CoE object 0x10F3. The entry Newest
Message (0x10F3:02) contains the subindex of 0x10F3, which contains the latest diagnostic message, e.g.
0x06 for diagnostic message 1.
