The channel menu is selected using the "Channel switchover" softkey. Use the horizontal
softkeys to select a channel group (HMI Embedded: max. 8, HMI Advanced: max.
24 channel groups); up to eight connections to channels in different NCUs can be set up in
one channel group. The "Channel menu" display shows all the current connections and the
associated symbol names.

Configurability

2 control units: 1 NCU
The diagram below illustrates the connection between two control units and one NCU. In this
case, there is a fixed assignment between the MCP and the NCU.
Figure 2-4
The control units, NCU and machine control panel are all either connected to the OPI bus or
the MPI bus. A homogenous network must be provided with respect to these components.
The illustrated configuration enables a large machine tool to be equipped with a control unit
on both the front and rear sides, for example.
