10.17 User-programmable IP interface
The user-programmable IP interface allows to send or receive any data via
Ethernet interface on the JC-120MC using TCP/IP or UDP/IP. When using this
feature, data processing is completely carried out by the application program.
The user-programmable IP interface allows the programmer to carry out data
exchange via Ethernet connections which do not use standard protocols, such
as FTP, HTTP, JetIP or Modbus/TCP. The following applications are possible:

Server
 Client
 TCP/IP

UDP/IP
To be able to program user-programmable IP interfaces the following
knowledge of data exchange via IP networks is required:
 IP addressing (e.g. IP address, port number, subnet mask)
 TCP (e.g. connection establishment/termination, data stream, data backup)
 UDP (e.g. datagram)
For communication via user-programmable IP interface, the programmer must
not use any ports which are already used by the operating system of the
controller. Therefore, do not use the following ports:
Protocol Port number Default value User
TCP Depending on the
FTP client
20 FTP server (data)
TCP 21 FTP server (controller)
