Output of error messages

With the function FN14: ERROR you can call messages that were pre-
programmed by the machine tool builder.

When the TNC encounters a block with FN 14 during program run, it
interrupts the run and displays an error message. The program must
then be restarted.

Input:

Example: FN 14: ERROR = 254

The TNC then displays the text stored under error number 254.

Example NC block

messages through the data interface, for example to a printer or to the
file %FN15RUN.A.
