Hello all, good morning.

We are experiencing a problem in a project where we use a CPU 1215C DC/DC/DC, KTP400 basic PN and a sinamics V90 servodrive on the network.

The problem come when we download the project with the HMI, PLC and V90 integrated in the network configuration, the network goes down and we are unable to connect to the HMI or PLC using that project.

When we use  a project with the HMI out of the network, conection between V90, PLC and PG work well.

We already reviewed IP Addresses and all are good. Compilation has no error or warning.

HMI FW Is 14.0.1.0

Have someone experienced something like that before?

What could be causeing the problem?

We are using TIA V15.

Thanks in advance.

Regards.

We couldn’t find the problem so we made HMI in different and linked to PLC with absolute addressed.
