PROFIBUS SLAVE interface
The embedded PROFIBUS SLAVE module is a complete PROFIBUS DP SLAVE. .
It contains all analog and digital components for a high performance PROFIBUS
extension circuit. The module is certified and has been tested for inter-operability
with many leading PROFIBUS master subassemblies. The onboard microproces-
sor automatically performs all PROFIBUS bus traffic thus completely reliving the
automation device’s main processor of any PROFIBUS protocol processing.
The PROFIBUS module supports a maximum PROFIBUS data width of 244 input
bytes and 244 output bytes as well as all rates from 9.6 KB/sec. to 12 MB/sec.
The PROFIBUS station address is set with the CoDeSys controller configuration.
Rotary switches S1 and S2 have no effect and can therefore not be used in an
application-specific manner.

Termination, S3 The PROFIBUS has a linear topology. It must be terminated at both ends. The
PROFIBUS SLAVE module has an integrated bus termination which can be acti-
vated by a DIP switch (ON position).
Baud rate The baud rate is automatically detected.
GSD file The PROFIBUS SLAVE master module is integrated in the CoDeSys controller
configuration with a GSD file. As of Version 1.0, this GSD file will be part of the
BERGHOF target installation package.
