Filtering/Data Extraction Configuration (Patent Pending)
This demonstrates that the program is effectively sending any data packet that is received by the DeviceMaster UP's
serial port back out it's serial port shortly thereafter. The actual delay is influenced by the cycle I/O specified for the
DeviceMaster UP in Step7 and the timing of the data entry. By changing the size of the modules inserted into the slots
in the DeviceMaster UP and changing the way data is written into the output memory, you can customize this
application as necessary.
Filtering/Data Extraction Configuration (Patent Pending)
Select your filtering mode(s):
•
Use String Filtering if:
‐
Your received data can be no greater than 128 bytes in length.
‐
Your received data is not in EPCglobal or barcode UPC/EAN formats or you do not want the DeviceMaster UP to
extract the RFID tag or barcode parameters.
‐
You want to filter and eliminate duplicate received messages.
•
Use RFID filtering if:
‐
You have an Alien or Intermec RFID reader or another reader that can provide RFID tag data is ASCII hex format
similar to either an Alien or Intermec reader.
‐
Your data is in EPCglobal format and you want the DeviceMaster UP to extract the RFID tag data parameters and
filter based on those parameters.
•
Use Barcode filtering if your barcode data is in UPC‐A, UPC‐E, EAN‐13, JAN, EAN‐14, or EAN‐8 formats and you want
the DeviceMaster UP to extract the barcode data parameters and filter based on those parameters.
PLC Filtering/Data Extraction
Under the Filtering/Data Extraction Configuration section corresponding to the desired serial or socket port:
1. Set To PLC Filter Mode to the desired mode.
2. For String (128 char max): set the Filter Age Time to how long after the last read you want an entry to be filtered. In
other words, after receiving a tag that matches the filtering criteria, no other tags that match the same criteria will be
sent until the amount of time specified in the Filter Age Time has expired.
3. Go to the appropriate discussion for your environment.
