4.1.4 Two-channel display
Assuming that the following requirements are met, you can display
channel information for 2 channels simultaneously with controls for
which 2 or more channels have been configured.
Prerequisites
• An M:N assignment is not active
• Two or more channels exist
• The machine data display is set for 2 channels
Representation
Two channels are shown 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.
Assuming that the above conditions are met, two-channel display
becomes immediately effective when the Machine operating area is
started.
Additional information
Two-channel display is simply a display method 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 two-channel display, no mode-
specific softkeys are required if channels in different operating modes
are displayed in the left and right panes.
Two-channel view
The division into two channel panes results in new supplementary
conditions for the information in each channel pane: In two-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 "program blocks" display is disabled if a part program is being
executed from an external source in one of the displayed
channels.
For selecting and changing operating modes, please refer to the
following chapter.
