General
These Instructions are supplementary to the ”Installation and Operating Instructions (Reference Manual) BM 100 A /
BM 100EEX ”. The details given there, in particular the Safety Information, are valid and should be observed. These
Supplementary Instructions provide only additional information for device operation and connection to a PROFIBUS-
PA fieldbus.
Attention: Please set the controller to manual mode before changing parameters of the BM 100 A.
Items included with supply
In addition to the standard scope of supply, these Supplementary Instructions for the BM 100 A with PROFIBUS-PA
interface plus a diskette with the available Profibus device data files (GSD files) of all KROHNE devices.

1. PROFIBUS-PA
The above diagram shows a typical instrumentation with PROFIBUS-PA devices in hazardous and non-hazardous
locations, including connection of conventional devices (e.g. with 4-20mA signals) to the PROFIBUS-PA.
The PROFIBUS-PA is normally connected to a segment coupler which, among other things, carries out the
conversion to the PROFIBUS-DP. Here, it needs to be noted in particular that the segment coupler is normally set to
a fixed baud rate on the DP side.
Further information on the planning and operation of PROFIBUS-PA networks is to be found in the KROHNE
brochure ”PROFIBUS-PA networks”.
