With the SENTRON powerconfig it is possible to connect with the SEAbus TCP protocol, but not with Modbus TCP. I have tried several Modbus Test Programs, but it seems that the TCP connection is refused. However I can ping the device over the LAN. Is there any special setting required (TCP Settings)?
