6. HOW TO COMMUNICATE WITH ID TAGS
(b) Writing to ID tags
1) By turning on the Write to ID Tag command signal (M1020), the subsequent Write
program is executed.
2) The Write command and the data required for writing are set in the buffer memory
(U0
\
G0 to G4) of the RFID module.
3) The data to be written to the ID tag are transferred to the buffer memory (starting
from U0 \ G100) of the RFID module.
4) The ID instruction execution request (Y14) turns on.
5) When writing to the ID tag ends normally, the ID instruction complete signal (X4)
turns on.
6) The ID instruction execution request (Y14) turns off.
7) The Write to ID Tag command signal (M1020) turns off.
