Providing TCP/IP services in an easy to use environment
TCP Open is a function block code that enables a PLC to communicate easily with any third-party TCP device, including RF tag readers, printers, bar code readers and even other PLCs.

Designed for use with the Modicon® Premium™ controller, the TCP Open software Derived Function Blocks (DFBs) provide TCP/IP services in an automation application.

• Easy to install - TCP Open software enables the programmer to construct a protocol within the application layer, allowing the PLC to communicate with any third-party device that is equipped with Ethernet TCP/IP.
• Easy to use - Programmers can employ these preset functions without any knowledge of programming languages such as C ++ or Java; programming is carried out directly using the DFBs in the desired automation language (ST, LD, FBD or IL).

Tracking goods through RFID
TCP Open software can also be used to facilitate tracking goods through RFID technology. The function blocks create an object in an object-oriented programming environment; the object automatically opens a communications channel to an RF tag reader, records the data and then closes the channel. The code block can be installed in a PLC’s programming software in minutes.
