6.2.3 Multi-master system
[6-2] PROFIBUS-DP multi-master system
In the multi-master operation, several masters are connected to one bus. They either form
independent subsystems consisting of one master of class 1 (DPM 1) each and the respective slaves
or additional masters of class 2 (DPM 2) for project planning and diagnostics. The input images and
output images of the slaves can be read by all masters. Writing the outputs can only be done by the
corresponding master of class 1 (DPM 1).
 Subsystem from master 1 and slaves 1 ... 3 with cyclic data transmission
 Subsystem from master 3 and slaves 4 ... 6 with cyclic data transmission.
 For the purpose of project planning and diagnostics, the master 2 can communicate with slaves 1 ... 6. The data is
transferred acyclically.
