Several Operator Panels on Several NCUs, Distributed Systems (B3)
Brief description
2.1.2.5

Configurability

NETNAMES.INI
When the M:N system powers up, it must be aware of the existing control units, NCUs and
communications links and their properties.
All this information is contained in the configuration file NETNAMES.INI, which is configured
before power up.
This present description is mainly intended to provide the necessary knowledge for correctly
setting up this configuration file for the M:N concept.
This means that:
● The hardware configuration is displayed
● The properties of the components are defined
● The desired switchovers/assignments are possible

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.

– 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).
