V90 communication with the device (drive or encoder) is faulty

Hello Dears.

I have a big trouble about v90 servo driver and CPU 1511T. I have a syncronization application in the project. I should be synchronize to another machines. When i tried run to the machine i am getting fault "communication with the device (drive or encoder) is faulty". I tried many things but i could not solve. When i made a topology connection and i selected IRT mode it does not work. Can someone help me?

 Hi Alihand,

Mode of communication through ?

When you look at each device configured in topology view, what is the first device in the daisy-chain of PN cables that stops working?  There's the first network cable connection problem.  You can use various tools like Proneta or Portal with device "Online & diagnostics" -> Profinet comms and see what each device is connected to at each port.

Once the physical wiring is exactly like the topology, things should improve.

After that, then the previously linked application examples should be reviewed to see how Siemens recommends performing certain tasks - and how to do it.
