Posted 10 Oct 2022 Can USB-A2 connect PLC through PROFIBus? Can profibus connect sub-stations directly for diagnosis? There is a 3152dp, which communicates with the sub-station through dp, and it is inserted into the dp head of cpu. It is not connected by automatic mode, but can be inserted into mpi port. Do you need any Settings? Share this post Link to post Share on other sites
