Diagnostic information can be read via the index 2020 of
the OD. The bus coupler provides 1 byte for diagnosis.
Index 2020 subindex 0 contains the highest subindex.
Highest subindex = 3
Index 2020 subindex 1 contains the length of the
diagnostic data.
W
Length = 1, if diagnosis is active
W
Length = 0, if diagnosis is not active
Index 2020 subindex 2 contains the diagnostic status.
W
00hex, no diagnosis is active
W
01hex, diagnosis is available
Index 2020 subindex 3 allows the diagnosis bytes of the
bus coupler to be read out. These are coded in a byte as
in Tab. 31.
