Identification systems with radio frequency technology (RFID)
RFID is the abbreviation for Radio Frequency Identification.
An RFID system consists of a data carrier, a device for reading the
data from the data carrier (read-write head) as well as other devices
which perform the transfer and processing of data (interfaces).
The transfer of data from the data carrier to the read-write heads is
undertaken using electromagnetic waves. This type of data transfer
is non-contact, without a visual contact and is insensitive to dirt and
temperature fluctuations.
The data carriers can be attached directly to a product. Further
terms used for the data carriers are TAGs or transponders. The data
content can consist of production and manufacturing data.
Important it that this data identifies the product. This is the
origination of the term “Identification System”.
A whole range of possibilities exist as the data content can be
changed by writing on the data carrier. Accordingly, the production
and manufacturing processes can be traced and monitored.
Logistics/distribution can be optimized.
The “Identifications Systems” can be integrated into (existing)
fieldbus systems (e.g. PROFIBUS). The integration of the respective
fieldbus system is undertaken with suitable interfaces.
Standardized software modules (e.g. the Proxy Ident Function Block
for PROFIBUS) enable simple system integration and
commissioning with different controls.
