The CP and cpu are in run mode with no failures. Thanks in advance for your support.

Please also check manual: CPU-CPU Communication with SIMATIC Controllers Regards, Towome

The solution was a restart of the server running ignition, maybe it was a bug from the software. Thanks again for your fast response.
