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 de-
vices. The onboard microprocessor 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 kbyte of I/O data. All baud rates
from 9.6 kbit/s to 12 Mbit/s can be set. All cyclic PROFIBUS services are available.
