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.
