Posted 9 Apr 2019 (edited) I have an 840Dsl with a built in 317F-3 PN/DP CPU. I cannot get my laptop to communicate plugging into the Profinet. I can get it to work with my laptop that has only Step 7, but not with my laptop that has TIA Portal 14 with S7 5.5.4. Is there something I need to do with the new software to enable communication? I also get the error in the attached picture when I boot up. Not sure if this is causing the issue. Thanks for any help! Edited 9 Apr 2019 by JPTenn Share this post Link to post Share on other sites
