Hi everyone!  
I am facing problem in configuring OPC UA - Client . In my Command Prompt the error message is red as follows: "09:28:30.568Z :client\_tcp\_transport :47 [NODE-OPCUA-E05] this transport protocol is not supported :ocp.tcp:". Hope someone can help me to fix this error! Thanks very much!

Hi,  
I've had the same issue. The issue is in the endpoint address. Reconfigure it using the complete address  
opc.tcp://:port  
You have mispelled opc and wrote ocp instead of the correct value.  
Regards,  
Marzio
