Antenna Configurations; Antenna Configuration Example - Siemens SIMATIC RF600 System Manual

After the separator, the goods are loaded onto pallets - each pallet is fitted with a tag. These
tags also contain user data that provides information about the sender and receiver of the
goods. Based on the data read by the SIMATIC RF670R reader, the pallets at the outgoing
goods gate are checked to make sure that they are intended for the receiver to which the
gate is assigned. Light barriers are installed to control the reader. Depending on the read
results of the reader, the outgoing portal opens, or it remains closed.

Antenna configuration example

The following diagram shows an application example for an antenna configuration of the
RF670R. The antennas are positioned at the height at which the tags are expected which
are to be identified. The maximum width of the portal that is recommended for reliable
operation is 4 m.
