4.1.4 Dual-channel display (SW 6.4 and higher)
You can display channel information for 2 channels simultaneously
with controls for which 2 or more channels have been configured.
Preconditions
· An M:N assignment is not active
· Two or more channels exist
· The display machine data is set for 2 channels
Representation
Two channels are represented side by side. One of these channels
has the focus.
The 1st channel (left pane) is the channel which was explicitly
selected in single-pane view This selection can also be made outside
the Machine operating area.
The right-hand pane displays:
· The associated channel configured in netnames.ini in section
[MULTICHANNEL] or, if not available
· The subsequent channel configured in the same group in
netnames.ini or, if not available
· The channel with the next highest number.
With the above mentioned conditions, dual-channel representation is
immediately displayed when the Machine operating area is started.
Other information
Dual-channel representation is a display for viewing the channel
information. Changes to NC channel data must still be made in the
single-pane display. See switchover. As changes to the NC channel
data are not entered via dual-channel display, there is no need for
mode-specific softkeys to show the channels in the different operating
modes in the left and right pane.
Dual-channel view
The division into two channel panes results in new boundary
conditions for the information in each channel pane: In dual-channel
view
· It is not possible to make entries in the relevant buffers in "MDI"
and "Teach-in" modes.
You have to switch to single-channel view to make entries.
· Traversing movements of the axes are not accepted.
· The display type "program blocks" is disallowed if a part program is
being executed from external in one of the displayed channels.
For selecting and changing operating modes, please refer to the
following chapter.
