Assigning system diagnostics/data transfer list to the slave PROFIBUS address
System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
• 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.

SEL=127: 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):
