Entering Traversing (Machining) Programs

The structure of traversing (machining) programs corresponds in all essentials to a
subset of the DIN 66 025 standard. The programs comprise a sequence of ASCII
characters, and may not exceed 1023 characters in total.
COM 266 stores traversing (machining) programs in data blocks. These blocks are
distinguished from one another by a data block number. Each data block
generated by COM 266 contains precisely one traversing (machining) program.
COM 266 enters the data block number in the traversing (machining) program's
header as program number. The total number of data blocks may not exceed 250.
Data block numbers must be in the range from 0 to 255.
Traversing (machining) programs can be written in two modes of representation:
• To DIN 66 025
• In Text mode
In addition, mode 10 ("TEACH-IN") allows you to generate traversing (machining)
programs automatically.
Please refer to Section 5.4 for more detailed information on traversing
(machining) programs.
Entering a traversing (machining) program
Press <F1> in the "FUNCTION SELECT" menu to screen the "INPUT" form.
You are already acquainted with this screen form from your "experiments"
with the "Input Machinedata" function.
Fill in the two input fields as follows:
Data block
Block-No.
Press <F1>, <F2> or <F3> to select the destination for your data (e. g.
<F3> for disk drive).
You are now in the "INPUT MACHINING PROGRAM" form.
