Displaying messages on the control's screen
You can also use the function
FN16: F-PRINT
to display any
messages from the NC program in a pop-up window on the
control’s screen. This makes it easy to display explanatory texts,
including long texts, at any point in the program in a way that
the user has to react to them. You can also display Q-parameter
contents if the protocol description file contains such instructions.
For the message to appear on the control’s screen, you need only
enter
screen:
as the name of the protocol file.
Example
96 FN 16: F-PRINT TNC:\MASK\MASK1.A/screen:
If the message has more lines than fit in the pop-up window, you
can use the arrow keys to page in the window.
To close the pop-up window, press the
CE
key. To have the program
close the window, program the following NC block:
Example
96 FN 16: F-PRINT TNC:\MASK\MASK1.A/SCLR:
If you output the same file multiple times in the
program, then, within the target file, the control adds
the current output after the previously output contents.
Exporting messages
The
FN 16
function also enables you to save the log files externally.
Enter the complete target path in the
FN 16
function:
Example
96 FN 16: F-PRINT TNC:\MSK\MSK1.A / PC325:\LOG\PRO1.TXT
If you output the same file multiple times in the
program, then, within the target file, the control adds
the current output after the previously output contents.
Entering the source or the target with parameters
You can enter the source file and the output file as Q parameters
or as QS parameters. For this purpose you previously define the
desired parameter in the NC program.
Further information: "Assign string parameters", page 455
In order for the control to recognize that you are working with Q
parameters, enter them in the
FN16-
function with the following
syntax:
Input Function
:'QS1' Set the QS parameter with preceding colon
and between single quotation marks
:'QL3'.txt Specify additional file name extension for the
target file if required
