8 - DeviceMaster UP Filtering and Data Extraction Reference Guide: 2000470 Rev. B Chapter 2. Data Extraction/Filtering Process

Filtering Criteria Definition

• The possible filtering criteria parameters for barcode filtering are Numbering, Company code, and

Product code.

• String filtering has no applicable filtering criteria. All serial/socket bytes are treated as raw data and

compared in the filtering process.

Example:

• A DeviceMaster UP is connected to an RFID reader.

• The PLC interface is enabled and is operating in RFID filtering mode. The PLC filtering criteria is set to

Company code and Product/Location code.

• The application port is enabled and it is also operating in RFID filtering mode. The application filtering

criteria is set to Company code, Product/Location code, and Serial Number.

• Six RFID tags are then read at one time. All have the same Company and Product/Location codes, but

different Serial Numbers.

- The PLC will receive one RFID tag because all have the same Company and Product/Location codes.

- The application will receive all six RFID tags because the Serial Number is included in the filtering

criteria and all six tags have unique serial numbers.
