System- and communication configuring D7-SYS - SIMADYN D 3-55
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.
Output Bit 16 Bit 15 Bit 14 ... Bit 5 Bit 4 Bit 3 Bit 2 Bit 1
D01 15 14 13 ... 4 3 (2) (1) (0)
D02 31 30 29 20 19 18 17 16
... ... ...
D07 111 110 109 100 99 98 97 96
D08 - - (125) ... 116 115 114 113 112
Table 3-23 Assigning system diagnostics/data transfer list to the slave PROFIBUS address
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):
Output Significance
D01 low byte
Status of the DP master: Stop (40h), Clear (80h),
Operate (C0h)
high byte Ident No. SS52 (high byte)=80h
D02 low Ident No. SS52 (low byte)=37h
high (irrelevant)
D03...D08
Table 3-24 Information specific to the master
SEL=3 ... 123: Slave diagnostics
• Output of slave diagnostics data.
• The SEL data entry corresponds to the slave PROFIBUS address.
