Filtering and Data Extraction Functionality (Patent Pending)
1.4.4.5. Filtering and Data Extraction Functionality (Patent Pending)
The DeviceMaster UP provides the following filtering and data extraction functionality.
• Filtering:
- String Filtering of up to 128 bytes of raw/ASCII data to both the PLC and/or application.
- RFID filtering of EPCglobal formatted RFID tag data to both the PLC and/or application.
- Barcode filtering of all UPC/EAN formatted barcodes data to both the PLC and/or application.
- Simplifies PLC and application programming tasks.
• Data Extraction:
- RFID data extraction extracts all parameters, such as company code, product code, and serial
numbers, from any or all of the 43 EPCglobal tag formats. It then transfers the data to the PLC and/
or application in a consistent and simple format.
- Barcode data extraction extracts the company, product, and numbering codes from UPC/EAN
formatted barcodes. It then transfers the data to the PLC and/or application in a consistent and
simple format.
- Simplifies PLC and application programming tasks.
• Environment specific support:
- Support for multiple RFID reader tag formats.
- RFID antenna grouping.
- Aging of filtered string/RFID/barcode entries.
- Discarding of unrecognized RFID and barcode messages.
