3.1.1 Direct fieldbus connection
Since the system bus is not master/slave oriented, new participants can be added to the fieldbus system
without special recognition of the central master.
All participants can communication with each other. It is thus possible to connect a PC directly to the
corresponding bus through a system bus interface module. All units connected can be addressed.

3.1.2 Fieldbus connection via PLC
If the system consists of a master and several slaves, it is often difficult to connect a fieldbus interface
module to the bus in parallel.
If the master is a PLC it can be possible to get to the fieldbus master via a PLC OPC server and then
address the drives. We offer a similar solution for the PROFIBUS-DP which uses a Simatic S7 PLC made
by Siemens as master.
