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 micro-
processor 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 kbit/s to 12 Mbit/s.
NOTICE
The PROFIBUS station address is set with the CODESYS controller configura-
tion. 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 activated by a DIP switch (ON position).
Baud rate
The baud rate is automatically detected.
GSD file
The PROFIBUS-SLAVE module is integrated in the CODESYS controller configuration with a GSD file. As of
Version 1.10.0, this GSD file will be part of the Berghof Target installation package.
Indicator LEDs
Four diagnostic LEDs indicate the current operating state and any error messages.
