SINUMERIK 840Di sl/840D sl/840D Operating Manual HMI-Advanced (BAD) - 01/2008 Edition
If "overstore" is active in single-channel view, the overstore function is
explicitly exited on switchover to two-channel view, provided 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 places; only the focus changes.
The M key will only switch between single-channel and two-channel
display in the current Machine operating area.
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 for a specific machine in the
PLC program.
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.
