• different, storage different
This means that the two files that have been compared with one another,
the contents differ from one another and they are stored at different
locations (NC or data management of HMI).
• When the files are selected in the list and the "Details..." button pressed,
ADDM opens the two different files next to one another. This function is
only available if different contents were identified in the files being
compared.
Data comparison
The offline and online data are shown alongside each other in the data
comparison. ADDM lists the different files goal-oriented and colour coded. In so
doing, missing lines are filled out with empty lines. This makes the differences and
correspondences very quickly and easily recognizable.
The code sequences in NC programs are given block numbers (N1234) to make
them easier to read. The block numbers can be renumbered with the control editor.
If this is the only change made to an NC program, ADDM detects that the whole
NC program is different as regards data backup. However, the actual code
sequences remain unchanged.
• For this case, the "N1234" button can be used to require ADDM to ignore
the block numbers in the comparison. Now, only the code sequences will
be compared and the actual differences marked.
• In larger files, you can jump to the next or previous difference with the
"Next" and "Previous" buttons.
