Hi,

I am sending some variables with a device via IEC 61850 MMS communication. When the data is sent from the IED's data model and without the use of RCBs, zenon client driver can receive the variables and read them. However, when I send the same data by RCBs with the same type of communication, zenon client driver does not receive anything and the query window just freezes.


Any ideas on why it freezes like this and how I can resolve this situation? Any help is appreciated. I am running the old 7.20 version. Thanks!
