FID system consists of a data carrier a device for Read and Write access to the data carrier as well as other devices used for data transfer and processing The transfer of data from the data carrier to the read write head occurs contact free with the help of electromagnetic waves The type of transmission is insensitive to dirt and temperature fluctuations The data carriers may be directly affixed to a product This is why the term mobile data memory is used as well Other terms for the data carrier are TAG or transponder The data content may consist of production and manufacturing data The data that identifies the product is important here This is where the description identification system comes from Further reaching possibilities are a result of the fact that the data content can be changed by writing to the data carrier Because of this production manufacturing processes can be retraced Logistics distribution may be optimized The identification systems may be integrated into existing fieldbus automation systems for example PROFIBUS DP The connection to the respective fieldbus system is done with suitable interface modules Standardized software components for example the Proxy Ident Function Block PROFIBUS DP make system integration and startup easy D101579 1208 BL ident PROFIBUS DP 1 3 The TURCK BL ident system Performance characteristics and applications of the BL ident system To meet the requiremen
