A screen form containing the parameter settings for the selected
cycle/contour appears on the screen.
Change the parameters.
The part program block is automatically inserted in the part program
with the new parameters.
The block numbering in the program shown in the editor is executed
again according to the values defined under the "Settings" softkey.
Once the softkey is selected another window opens. Specify the
"Block number" and the "Increment".
The coordinate system and the technology to be used are set via the

It is possible to switch between channels when several are in use.
Since individual channels may be assigned to different mode
groups, a channel switchover command is also an implicit mode
switchover command.
If the selected channel is located on another NCU (m:n link), the HMI
Embedded is switched implicitly to this NCU.
When a "Channel menu" is configured, all existing communication
links to other NCUs plus the associated channels are displayed on
softkeys.
The following three channel states can occur in each mode:
1. Channel reset
The machine is in the initial state, e.g. after power-on or after end
of program. The initial state is defined by the machine-tool
manufacturer in the PLC program.
