Master PROFIBUS address
• PROFIBUS address of the master which had parameterized this
slave.
If this slave is not parameterized, then FFh is used.
Identification number
• High/low byte:
This identifies the slave type.
All additional diagnostic data are slave-specific.
Generally (standard DP slave) the diagnostic blocks follow: Device-
related, identification-related and channel-related diagnostics. Not all
slave-specific diagnostic blocks must be available.
Each block is preceded by a header byte. The diagnostics block is
identified by bit 7 and bit 8:
