Defaults
The following defaults are applied if no NETNAMES.INI configuration file has been copied
into the HMI Embedded/OP030 or if the file cannot be interpreted:
● The bus type used is detected automatically.
● PCU has address 1.
● OP030 has address 10.
● NCU and PLC both have address 13 for an OPI bus.
● NCU has address 3 and PLC address 2 for an MPI bus.
If the network configuration actually corresponds to these default settings, then it is not
necessary to explicitly generate and load the NETNAMES.INI file. If a special file is created,
however, it must correspond exactly to the network configuration.

Use the horizontal softkeys to select a channel group (max. 24), 8 links to channels on
different NCUs can be set up in each channel group.
The "Channel menu" display shows all the current communication connections and the
associated symbol names.
