PROFIBUS DP/PA
Linking Device
(LD 800P)
(cont.)
The way in which LD 800P works is essentially transparent.
This means that PROFIBUS DP masters have direct access
to PROFIBUS PA slaves. This offers the following
advantages:
• No configuration of the Linking Device is required
• PROFIBUS PA slaves can be treated like PROFIBUS
DP slaves
• There is no PROFIBUS DP address setting on the
Linking Device
• Because of this, there is no restriction on the amount of
data to 244 bytes of I/O data per PROFIBUS PA
segment for the PROFIBUS PA.
See Figure 120 on page 414 for LD 800P Interface. For
more information see fieldbus documentation.
