Greetings!

That's why I don't understand why we get 315 Bytes and the other 2 Bytes we want to read and that are transferred just as the other ones are not visible. Gree...

Hello everyone! We have the problem right now, that we can only read (including) 315 Bytes with our ProfiNet GWs. If we read after that with piTest, we can only see zeros, no matter what we write on those addresses. We tested several modules, everywhere we tested we get the same result. Does anyone ...

Hello Amar,

thank you for the quick response and advice! I was finally able to test this out on the system and it seems like it works just fine.

This setup works just as expected and we receive valid data on the 64 Input Words. However, we expect more data from the slave and have problems configuri...
