Single-channel view
If "overstore" is active in single-channel view, the overstore function is
explicitly exited when switching to dual-channel view if this is
permitted by the NC. Otherwise, single-channel view is retained.
Channel switchover is effective for the pane which has the focus.
If exactly two channels are configured, the channel windows do not
switch over; only the focus changes.
Changeover
The M key will only switch between single-channel and dual-channel
display in the current Machine operating area.
4.1.5 Operating mode selection/change
Function
The defined modes for operating a SINUMERIK control system are
Jog, MDI and Automatic. They are selected via the MCP or by means
of softkeys.
Machine manufacturer
Whether the requested mode can be accessed and the manner in
which it is accessed can be configured machine-specifically in the
PLC program.
Mode change
Not all mode changes are permitted.
An error message is output if a mode change request is rejected by
the system. The error message will indicate the error cause and
possibly the remedy.
