Hi again, Many thanks for those replies...I didn't ask quite the right question. Under the guise of 'asset security' I have had a 'gun put to my head' to hand over "back up copies" of PLC programs to someone who fancies he might use those to have a play and make 'improvements' What I want to do is take each of the programs that are presently labelled, commented, symbols named and commented, etc, and generate a bare-bones ladder with nothing but the addresses, the logic and the automatic symbols. I am hoping to do this file by file, not section by section or rung by rung. Then, if they are smart enough, they can work out what all the bits are for, add the label and comment info, and play around -by all means, be my guest! Symbol names - easy to do -select all, and delete. Ladder sections- I can only find a one by one method...there are too many sections and rungs of those. I have tried to create a blank .idx file and import /overwrite using that -without success. The other method I have contemplated is to generate a mnenomic listing and save just the code, Can anyone suggest a quick way to do that? Kind regards
