Chapter 2. Data Extraction/Filtering Process
The data extraction and filtering processes work together to offer:
• String filtering for raw/ASCII data up to 128 bytes in length.
• RFID data extraction and filtering.
- Extraction of all tag parameters from the 43 possible EPCglobal formats including:
- Encoding scheme
- Filtering value
- Company code
- Product/Location code
- Serial number
- Extraction of the antenna number located in the RFID reader tag ASCII string. (Included with the
RFID tag data parameters).
- Selectable filtering criteria to both the PLC and application based on these parameters.
- Selectable RFID antenna groupings.
- Selectable RFID reader formats.
- Discarding of unknown data to the PLC and/or application.
• Barcode extraction and filtering.
- Extraction of all barcode parameters from valid UPC/EAN barcode formats including:
- Numbering code
- Company code
- Product code
- Selective filtering criteria to both the PLC and application based on these parameters.
- Discarding of unknown data to the PLC and/or application.
- Selectable barcode data formats.
2.1. Filtering Criteria Definition
The filtering criteria is defined as the
parameters used in the filtering
process.
• As the number of selected filtering
criteria options increases, the
number of serial/socket messages
that can potentially pass filtering
increases.
• As the number of selected filtering
criteria options decreases, the
number of serial/socket messages
that can potentially pass filtering
decreases.
• The possible filtering criteria parameters for RFID filtering are Antenna, Encoding Scheme, Filtering
Value, Company code, Product/Location code, and Serial Number.
