System Setup
The figure below shows a simple RFID system. This user manual describes the
setup, installation, and programming required to get this system running.

Tags are attached to objects that need to be tracked. The tags hold important
information about the object. An RF transceiver reads and/or writes information
to the tags when the tag moves within the transmission envelope of the
transceiver (dotted ellipse). The physical size of the transceiver is directly related
to the size of the transmission field. The larger the transceiver, the longer and
wider the antenna field is. Please see transceiver instruction sheets for antenna
field sizes.
The transceivers are connected to a special RFID EIP interface block. The
distribution block has an EtherNet connection to an EtherNet switch. An L35E
CompactLogix controller and a personal computer also have EtherNet
connections to the EtherNet switch.
