Kaulquappe Posts: 3093 Rating: (324)	Hello Shoaib, due to my experience the main difference isthe data throughput. TCP native communication via the Ethernet interface of the CPU is at least twice as fast as via CP. As the CPs/CPUs have got different scopes of operation you have to check the features you need for your application. Depending on the used protocol the necessary standard functions differ as well as the connection parameterization in NetPro. As the CPUs get more and more powerful, it is not always necessary to have a CP that handles the protocol things, the CPU itself is able to do it. Regards, Kaulquappe
