Hi!  
I need to work with Modbus TCP, so I am using the function “MODBUS\_TCP\_Init”, but in the description of this function it says that  
“It initializes the MODBUS TCP system. It does NOT initialize the TCP/IP connection.”

So, my question is how does one initialize the TCP/IP connection?

Thanks in advance
