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.
