PROFIBUS DP Communication

8.1
General information
8.1.1
PROFIBUS DP interfaces of the MCI board
There are two PROFIBUS DP interfaces on the MCI board:
●
Interface X101: PROFIBUS DP
The NC only has direct access to this PROFIBUS interfaces. Therefore all PROFIBUS
drives and NC-specific I/Os, e.g. MCPs with handwheels, must be connected via this
interface.
The NC also derives the position control cycle clock from the parameterized equidistant
PROFIBUS cycle clock of this interface.
The interface is operated exclusively in the "DP-Master" mode.
●
Interface X102: MPI/DP
This PROFIBUS interface is only available to the PLC. It can also be operated in "DP
Master" or "DP Slave" mode.
8.1.2
PROFIBUS DP with Motion Control option
PROFIBUS DP
PROFIBUS DP is an international, open fieldbus standard, which is specified in the
European Fieldbus Standard EN 50170 Part 2. PROFIBUS DP is optimized for fast, data
transmission at the field level for time-critical applications.
The components communicating via the PROFIBUS DP are categorized as either master or
slave components.
1.
Master (active bus device)
Components operating on the bus as master determine the data exchange on the bus
and are therefore also designated as active bus devices.
There are two classes of master:
–
DP master, Class 1 (DPMC1):
Central master devices are thus designated, which exchange information with the
slaves in specified message cycles.
Examples: SIMATIC S5, SIMATIC -, etc.
