Posted 10 Jul 2014 (edited) Hi, I have a question about DP communication. That is the relation among the hardware configuration, FB, and DB declaration. Refer the attached pictures for understanding my question. The testing item is Yamaha robot machine using the DP communication. How can those communicate each other by any address mapping? Which information should I give the Yamaha engineer for the address mapping? Thank for your detailed explanation in advance. (Especially the address declaration of them) Edited 11 Jul 2014 by Tom749 Share this post Link to post Share on other sites
Posted 17 Jul 2014 It is simple the inputs on the plc are outputs for the yahama robot. And vice-versa. They need to come out with an interface. You should do the follwoing: - Request to the yahama eng. what he needs as sginals (outputs) and what he can offer on the inputs. - Then the guy on the plc side should map the inputs and he can use them on in ladder logic. In the end those inputs are singnals from the Yahama robot. Share this post Link to post Share on other sites
