PROFIBUS MASTER interface
The embedded PROFIBUS MASTER bus module is a PROFIBUS DP master.
The module has been tested for conformity with the PROFIBUS standard and for
inter-operability with many leading PROFIBUS slave devices. The onboard micro-
processor automatically performs all PROFIBUS bus traffic thus completely reliving
the automation device’s main processor of any PROFIBUS protocol processing.
The PROFIBUS MASTER module supports a max. of 125 slaves with up to 3 KB of
I/O data. All baud rates from 9.6 KB/sec. to 12 MB/sec. can be set. All cyclic
PROFIBUS DP services are available.

All application and diagnostic data are set up via the CoDeSys controller configu-
ration or are provided by the application. Therefore, the diagnostic interface can-
not be used in an application-specific manner.
