Simple communication via Ethernet in RFID applications using TCP/IP
Siemens Industry, Inc. has released a new communication module specifically geared to connecting RFID (Radio Frequency IDentification) read/write devices to Ethernet networks.
According to Ed Housler, business manager for Siemens, the Simatic RF182C is designed for Ethernet communications environments, is based on TCP/IP protocols, and uses state of the art XML messaging technology. “The goal with this device is to simplify Ethernet communications for factory floor RFID applications. We are seeing more demand for Ethernet connectivity. This module gives users more flexibility and really helps them take advantage of RFID technologies in the factory environment,” he says. Simple, yet powerful XML command/response telegrams mean a myriad of integration options.
The RF182C offers users several new features, including: dual RFID channels that ensure real-time operation at the dynamic read points and XML-structured data records that make programming easier. The RF182C offers a web processor where a browser interface can connect and be leveraged to manage firmware updates and other functions.
“Integrating XML means the communication module can be easily integrated in a PC environment or connected to commercially available controllers,” says Housler. “Additionally, the RF182C is highly ruggedized, with an IP67 rating. Since it doesn’t need the protection of a control cabinet it can be installed directly on the factory floor or into the process itself. It boasts a powerful hardware configuration that ensures rapid data communication with the read/write device and is easy to service or replace without interrupting the network because the Ethernet parameterization data is saved to the connection block.”
The RF182C is intended for use in machine building, conveyor systems, assembly lines in the automotive and supplier industries as well as in ancillary assembly lines. The integrated dual port Ethernet switch design of the RF182C’s connection block allows for extremely flexible bus topologies to be designed.
