Profibus DP provides an extensive set of diagnostic functions for fast error
localization. Diagnostic messages are transferred via the bus and collected
by the master.
As a further function, the device-specific diagnostic of the DP-V1 have
been enhanced and divided into the categories interrupts and status
messages.
DP-V0 provides the basic functionality of DP, including cycle data
exchange as well as station diagnostic, module diagnostic and channel-
related diagnostic.
Data is transferred cyclically between the DP master and the DP slave by
means of transmit and receive buffers.
