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!
