System features

General information
The following applies to all M:N applications in which the "control unit management" option is
not implemented.
Note
This section does not apply to the HT6, since only one HT6 can ever be operated on an
NCU without control unit management.
System features
● The connection between the PCU and the NCU is implemented via:
● The following configurations are possible:
● One of the panel fronts must be an OP030.
● Two MCPs and one HHU can be connected to the MPI or OPI on one NCU.
● The necessary configuration in the NC for the connection of MCPs/HHUs is defined using
● Addresses must be specified in the case of data exchange between PLCs via Profibus
● The maximum number of bus nodes is 32.

– MPI bus (187.5 Kbaud)
– OPI (1.5 Mbaud):
– "One operator panel front and up to three NCUs"
– "One operator panel front and up to four NCUs"
– "Several operator panel fronts and NCUs"
Connection of operator panels via the OPI interface (X101 on NCU) and the MPI
interface (X122 on NCU).

DP or for global data (double addressing) with PLC-CPU 315 and higher.
The following applies: NC address = PLC address + 1.
