7.2.1 General information on data communication via TCP/IP
The IC-KP-B17-AIDA1 device was designed to act as a TCP/IP server, which means that the
so-called client must send a command to actuate each function.
Communication is established via the TCP port 10000. Programming control software requires
accurate knowledge of TCP/IP sockets.
The following illustration shows the basic communication flow:
A connection must be established on the TCP/IP level before data can be exchanged. From this
point onwards, commands can be sent from the client to the IC-KP-B17-AIDA1 device.
