Instance Attribute Definitions
Attribute 27
To PLC Filter/Data
Extraction Mode
The filter/data extraction mode to be employed on data to be sent to the PLC.
•
0 = Off
•
1 = String (128 char max) - Raw/ASCII data is filtered up to 128 characters (or
bytes) in length.
•
2 = RFID (EPCglobal formats) - RFID data in any of the EPCglobal formats is
filtered, the associated parameters is extracted, and the extracted data and
RFID tag is sent to the PLC in a specified format.
•
3 = Barcode (UPC/EAN formats) - Barcode data in specified UPC/EAN formats
is filtered, the associated parameters is extracted, and the extracted data and
barcode is sent to the PLC in a specified format. See the
in Attribute 41 on Page 28.
See the
DeviceMaster UP Filtering and Data Extraction Reference Guide
for further details.
Attribute 28
To Application Filter/
Data Extraction Mode
The filter/data extraction mode to be employed on data to be sent to the application.
•
0 = Off
•
1 = String (128 char max) - Raw/ASCII data is filtered up to 128 characters (or
bytes) in length.
•
2 = RFID (EPCglobal formats) - RFID data in any of the EPCglobal formats is
filtered, the associated parameters is extracted, and the extracted data and
RFID tag is sent to the application in a specified format.
•
3 = Barcode (UPC/EAN formats) - Barcode data in specified UPC/EAN formats
is filtered, the associated parameters is extracted, and the extracted data and
barcode is sent to the application in a specified format.See the
in Attribute 41 on Page 28.
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.
See the
DeviceMaster UP Filtering and Data Extraction Reference Guide
for further details.
Attribute 29
Discard Unrecognized
Data Mode
This attribute controls what to do with unrecognized RFID or barcode data.
•
0 = Off - Send unrecognized data to the PLC and/or application.
•
1 = Discard unrecognized data to the PLC. Allow sending of unrecognized data
to the application.
•
2 = Discard unrecognized data to the application. Allow sending of unrecognized
data to the PLC.
•
3 = Discard unrecognized data to both the PLC and application.
Attribute 30
RFID Antenna
Grouping
This attribute 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. The possible groupings are:
