Flexible RFID system features Profibus-DP connectivity
29 February 2012
ifm electronic has introduced the DTE100 RFID evaluation unit with integrated Profibus-DP interface. Also featuring a web server, the new platform can be used in production environments to track tooling, for quality assurance procedures, in assembly/handling operations and in conveying for part tracking. The DTE100 is a compact device in a robust housing making it suitable for installation directly on a machine.
The DTE100 acts as the evaluation unit for up to four attached RFID antennas and transmits the data collected via its Profibus-DP interface. Set-up and integration into the higher-level automation/ process control is a simple procedure, and program examples are supplied.
The four connections are multi-purpose; so where only one or two RFID antenna inputs are needed, the ports can easily be used as standard digital inputs or even as an output.
The range of available antennas also makes any identification task easy, with systems for different read/write distances and data rates. The range includes LF transponders with up to 2kbit-memory as well as HF transponders with 16kbits of FRAM which can be rewritten an unlimited number of times. All connections are industrial standard M12.
