Posted 20 Oct 2011 Hello I am editing a S7 300 project and dont know wath "PD_I3.1" do or stands for? I cant make it work in my new S7 300 CPU315-2 PN/DP, but in the old S7 300 COU315-2 DP it worked. I have copied the old project to a new, can there be somthing i havent copied? Share this post Link to post Share on other sites
Posted 20 Oct 2011 It looks like it is a "Symbol" name for input I3.1 - Have you copied the symbols for the project? Share this post Link to post Share on other sites
