•
The 8 words are bit-coded.
•
Each bit is assigned a slave with its PROFIBUS address
corresponding to the following table.
•
If the bit for the associated slave is set, then the slave has provided
diagnostics data.

Data transfer list
•
The data transfer list provides an overview of the slaves which were
involved with data transfer within a configured time
(COM PROFIBUS).
•
The 8 words are bit-coded as for the system diagnostics.
•
If the bit for the assigned slave is set, then data is being transferred.
SEL=128:
Master status
•
Outputs information specific to the master (for users, the low byte of
D01 is relevant; the significance of the other outputs has been
documented, but hasn’t been explained in any more detail):
