Filtering Modes
5.1. Filtering Modes
The following settings are available for the filtering modes in the web page PLC
interface.
The application filter mode can be set independently of the PLC filtering mode. The only exceptions are:
• If the PLC filter mode is set to RFID, the application filter mode cannot be set to Barcode.
• If the PLC filter mode is set to Barcode, the application filter mode cannot be set to RFID.
5.2. RFID Antenna Grouping
This setting is applicable only to RFID filtering and only if the Antenna Filtering option is enabled. It allows
the DeviceMaster UP to filter RFID tags based on antenna groupings.
When Antenna Grouping is enabled:
• Tags that have the same filtering criteria (i.e. company and product number), received
from antennas within the same group will be filtered as if they are the same entry and
will be treated as one filtering entry.
• Tags that have the same filtering criteria (i.e. company and product number), received
from antennas not within the same group will be filtered as if they are different
entries.
The possible groupings are:
Filtering
Modes
Applicable Filtering Criteria Parameters Description
Off None
No Filtering of any type. Maximum packet
sizes apply.
String Up to 128 bytes of raw/ASCII data.
No data extraction. Messages are limited to
128 bytes in length. Any messages exceeding
128 bytes will automatically be truncated to
128 bytes.
RFID
Antenna Number: From RFID reader/scanner.
Encoding Scheme: From RFID tag data.
Filtering Value: From RFID tag data.
Company Code: From RFID tag data.
Product/Location Code: From RFID tag data.
Serial Number: From RFID tag data.
RFID data in any of the EPCglobal formats
will be filtered, the associated parameters will
be extracted, and the extracted data and RFID
tag will be sent to the PLC/application in a
specified format.
Barcode
Numbering: One to three digits, depending on
barcode format.
Company Code: Length in digits varies
depending on the format.
Product Code: Length depends on the format.
Barcode data in UPC/EAN formats will be
filtered, the associated parameters will be
extracted, and the extracted data and barcode
will be sent to the PLC/application in a
specified format.
