Nbr 1 (with both MPI and DP connection) is Master, Nbr 2 is slave. BR Goran |

Hello Goran, If both CPU are Master, you must use DP/DP coupler. Then routing is not possible. You'll have access only to the connected CPU. In other case - first CPU is a Profibus Master and second is Profibus Slave. PG will be connected to the Master CPU via MPI. In your picture you didn't asign exactly the type of CPU. For this reason, go to What are the requirements for using the S7 routing function and which modules can you implement? and check if CPU supports routing function. You can use instructions from this link also to build the routing. Fanaly you must "reach" this situation click. I's also possible to connect to the Slave CPU and use it for routing. (more details in S7 routing via PROFIBUS with S7-300 ) Hope this will hepls. regards |
