Working with the TNCguide
Calling the TNCguide
There are several ways to start the TNCguide:
Press the HELP key if the TNC is not already showing an error
message
Click the help symbol at the lower right of the screen
beforehand, then click the appropriate soft keys
Use the file manager to open a help file (.chm file). The TNC can
open any .chm file, even if it is not saved on the TNC’s hard disk
If one or more error messages are waiting for your
attention, the TNC shows the help directly associated
with the error messages. To start the
TNCguide, you
first have to acknowledge all error messages.
When the help system is called on the programming
station, the TNC starts the internally defined
standard browser (usually the Internet Explorer), or
otherwise a browser adapted by HEIDENHAIN.
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 TNC 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, and click: The TNC opens the TNCguide. If no
specific part of the help is assigned to the selected soft key, the
TNC opens the book file
main.chm, in which you can use the
search function or the navigation to find the desired explanation
manually
Even if you are editing an NC block, context-sensitive help is
available:
Select any NC block
Use the arrow keys to move the cursor to the block
Press the HELP key: The TNC starts the help system and
shows a description for the active function (does not apply to
miscellaneous functions or cycles that were integrated by your
machine tool builder)
