11.2.1.1 Subindex 0: Highest supported subindex
The diagnostic history can contain at most the number of diagnostic messages specified
in subindex 1: Maximum Messages. These can be retrieved starting with subindex 6.
Subindex 0 indicates the highest subindex under which a diagnostic message is stored.
11.2.1.2 Subindex 1: Maximum Messages
The diagnostic history can contain as many diagnostic messages as specified here. The
maximum value is 64.
11.2.1.3 Subindex 2: Newest Message
Using the subindex 2, you can retrieve the subindex in the diagnostic history under which
the latest diagnostic message is stored. The value should be between 6 and 69. If no di-
agnostic messages are currently stored, a value of 0 is returned.
11.2.1.4 Subindex 3: Newest Acknowledged Message
This subindex contains the subindex of the newest acknowledged diagnostic message. It
can be both read and written. In both cases, the meaning of the values depends on the
current mode. The modes are overwrite mode (subindex 5, bit 4 = 0) and acknowledge
mode (subindex 5, bit 4 = 1).
