Diagnostics in the IL PB BK DI8 DO4 format
This diagnostic format consists of the following blocks:
1
PROFIBUS standard diagnostics
2
ID-specific diagnostics
3
Status diagnostics (terminal status)
4
Channel-specific diagnostics
5

The header bytes are used to distinguish between all blocks.
From block 2 onwards the diagnostic telegram is dynamic. The individual number of bytes
in a block depends on the station structure.
