Hello Orcaof DP_SEND and DP_RECV are only required if you use a CP342-5 as the DP Master interface in an S7-300 so my first question is: What DP Master do you intend to use on your S7-300 (CPU's onboard DP port or CP342-5)? Either way, the one thing you MUST have is a GSD file for your DP Slave which is then imported into TIA Portal and used for the DP Slaveconfiguration (see for example HERE and HERE on how to import GSD files in TIA Portal and http://www.profibus.com/products/gsd-files/for more on GSD files in general). The big (and second) question is: Have you created a GSD file for your own "arduino card with a homemade profibus card on it"? I hope this helps |
