Radio Frequency Identification (RFID) is a technology designed to allow objects, animals and even human beings to be identified, located, and tracked using radio frequency signals.
These radio waves transmit data from the tag to a reader, which then transmit the information to an RFID computer program.
The history of RFID can be traced back to World War II, when it was used by the British to identify friendly aircraft.
The technology has developed over the years and is now used in a wide range of applications.
There are many pros to RFIDs. They are convenient and easy to use, and due to their ruggedness can be used in harsh environments.
ifm’s ANT600 antenna is ideal for long writing / reading distances. A typical application is product tracking in the production process.
The ANT600 may be used for storing e.g. production data or quality parameters on the ID tags.
In material logistics, the RFID system can easily determine whether the material and quantity of material match the production order.
In plant control, product-specific machine parameters can be read from the ID tag attached to the product.
The transmitting power can be adjusted in order to define different ranges.
The RFID antennas are designed for connection to the compact ifm evaluation unit DTE10x.
This unit offers four M12 sockets for connection of up to four RFID antennas.
Optionally, unused RFID inputs can also be used for the control of outputs or the detection of digital input signals.
Two digital sensors can be connected to each socket set as an input and an actuator to each output.
For communication to the higher-level controller, the DTE10x has an EtherCAT, Profibus, Ethernet TCP/IP, EtherNet/IP or PROFINET interface, depending on the design.
Application example: RFID for detection of material during manufacture and of inflow and outflow in high-bay storage facilities
The ifm RFID solution with connection to a Siemens PLC is used as a system.
The ifm components DTE 100, ANT600 and the RFID tag E80383 are used.
The task consists of identifying an article marked with a 14-digit variable code and an order number.
Benefit for the customer: the indication and booking of the material inflow / outflow in real time closes the gap between the material stock in the warehouse and the stock indicated in the customer’s software system.
The system always knows the location and number of products of all types; theres no need for complex documentation and lost paperwork is a thing of the past.
The transponder is firmly connected to the tank. long distances are no problem thanks to the 200 mm writing / reading range of the RFID antenna.
