5–2 Profibus Parameter Descriptions and Data Protocol
Profibus-DP Data Protocol
This chapter provides you with the PD1 Module Data Protocol
information.
Data from Profibus-DP Master
to PD1 Slave
The Profibus Telegram consists of several bytes (words) according to
the following table:
Table 5.A
Data from PD1 Slave to
Profibus-DP Master
Table 5.B
116 4 Read only [PD1 SW Version]
This parameter indicates the software version of the PD1 option.
The number is in the form of xx.yy where xx indicates the major revision level and yy
indicates the minor revision level.
0.00 to 10.0 1.0
Note: P57 [Program lock] may be set to 1 (locked), but parameter programming via network will still be
possible.
