Diagnostic information

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.
Length = 1, if diagnosis is active
Length = 0, if diagnosis is not active
Index 2020 subindex 2 contains the diagnostic status.
00hex, no diagnosis is active
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 Table 29.
