Posted 23 May 2017 (edited) Hi, Could someone explain or direct me to better understand the RS Logix 5 comparison tool? I'm comparing multiple PLC codes and having a little bit of trouble understanding what the concept of "deletion", "insertion" etc are portraying. Since, some rungs are labelled 'deleted' and 'inserted' in the comparison, however, the rung labelled deleted seems to exist in the actual code?

Posted 23 May 2017 It's been a while since I used the Compare tool, but as far as I remember, sometimes it will tell you a rung is "deleted" even when it seems to exist in the actual code, if the rung has been modified. In some cases the rung has been modified and not deleted, but the Compare tool will tell you it's been deleted. Share this post Link to post Share on other sites
