Scanning for Ideas: FRAM-based RFID with built-in I/Os

The BL Ident system from Turck, Minneapolis, for reading RFID tags or discs, is flexible in that it lets users add I/O modules and up to eight channels of RFID. It conforms to ISO 5693 13.56-MHz HF standard. The system can be added to existing platforms and supports several different configurations, including Profibus-DP, DeviceNet, Modbus-TCP, Profinet, and EtherNet/IP. Standard nonprogrammable and CoDeSys programmable gateways can have either IP20 or IP67 ratings.

BL Ident works with a variety of differently shaped FRAM-based RFID tags and read/write intervals can be from 5 to 500 mm. And tags can be rewritten and reused an unlimited number of times, theoretically. Tags can survive temperatures up to 210°C and need no cool-down period for read or write operations, which reduces downtime. The system can read and write simultaneously at 0.5 msec/byte, with production speeds of up to 10 msec/byte at distances up to 500 mm.

Configuration software can help users choose RFID equipment by simulating an application’s parameters and values, so that users need not make complicated calculations or evaluate hardware compatibility issues.
