Chapter 5. Filtering Configuration Settings
Filtering is the process by which the DeviceMaster UP can control the number of similar received data
messages sent to a PLC and/or application. The goal of filtering is to prevent extra, or unwanted, messages
from being sent to the PLC and/or application.
The DeviceMaster UP provides filtering with the following capabilities:
• Filter up to 256 filter entries at one time per port.
• Filter raw/ASCII String data up to 128 bytes in length.
• Allows the PLC and application to operate in different filtering modes. (i.e. The PLC filtering mode may
be RFID while the application may have its filtering set to Off or String filtering.)
• Independent filtering criteria for both the PLC and application.
• RFID Antenna grouping. Allows the RFID filtering to work with numerous antenna configurations.
• Interfaces to different RFID readers.
• UPC/EAN barcode filtering.
• Aging of filtered entries. Allows a user to set how long a filter entry will be filtered after it has last been
read.
• Discarding of unrecognized messages in RFID and barcode filtering modes.
All filtering and data extraction functionality can be configured separately for both the PLC and application
socket interfaces using the DeviceMaster UP Filtering/Data Extraction web page interface (below).
