Working with TNCguide

Calling TNCguide
There are several ways to start the TNCguide:
Press the HELP key.
Click the help symbol at the lower right of the screen
beforehand, then click the appropriate soft keys
Open a help file (CHM file) via the file management. The control
can open any .chm file, even if it is not saved in the control's
internal memory
On the Windows programming station, the TNCguide is
opened in the internally defined standard browser.
For many soft keys there is a context-sensitive call through which
you can go directly to the description of the soft key's function.
This functionality requires using a mouse. Proceed as follows:
Select the soft-key row containing the desired soft key
Click with the mouse on the help symbol that the control
displays just above the soft-key row
The mouse pointer turns into a question mark.
Move the question mark to the soft key for which you want an
explanation
The control opens the TNCguide. If there is no entry point
for the selected soft key, then the control opens the book file
main.chm. You can search for the desired explanation using full
text search or by using the navigation.
Even if you are editing an NC block, context-sensitive help is
available:
Select any NC block
Select the desired word
Press the HELP key.
The control opens the Help system and shows the description
of the active function. This does not apply for miscellaneous
functions or cycles from your machine manufacturer.
