Technical information

RFU6xx FB for

GX Works 2 (PNDP)

Page 29

The read tag functi

on is completed as soon as bit “ReqDone” = TRUE. The parameter

Mode_UII shows the UII of the selected transponder.

The tag content is available in array "ReadTag_Data" of the

“stRFUData” variable. The

"ReadTag_DataLength" variable specifies how many words have been received and valid.

Figure 22: Read tag content

Please note that the first byte of the word (LSB) contains the first data byte of the RFID tag.

Figure 23: TAG content from the SOPAS view

Note

In the example program, this data will be converted automatically into an
ASCII string.
