Siemens Communication via Ethernet in RFID Applications

The Siemens Industry Automation Division has developed a communication module for the connection of RFID (Radio Frequency Identification) read/write devices to Ethernet. The new product is designed for Ethernet communication by means of TCP/IP protocol and supplements the modules already available for Profibus and Profinet.

According to Siemens, the Simatic RF182C communications module is suitable for the read/write devices of all RFID systems except Moby R. The high IP67 degree of protection facilitates distributed installation outside the control cabinet directly in the plant process and rapid commissioning is possible with the plug-in connection technology. Up to two RFID read/write devices can be connected in parallel to the basic unit. The RF182C can be integrated in the field level using one of three different technologies - the RJ45 push-pull plug, M12 7/8" 5-pin or M12 7/8" 4-pin connection blocks.

Simatic RF182C is programmed with standard XML commands. The communication module can be integrated in a PC environment or connected to commercially available controllers. Siemens also claim the basic unit can be replaced during servicing without interrupting the network.
