• Timing Chart (CIO n = CIO 2000 + (10 x 0) = CIO 2000)
• If communications with the RF Tag fail, the bits in the Results Information (CIO n+8) will turn ON
accordingly, and the error code will be placed in the Processing Results Monitor (CIO n+9). The
previous read data will not be changed.
• To confirm the execution results from the user program, use the ON status of the Normal End Flag or
Error End Flag. These flags show the Unit status.
• Do not turn ON the Command Execution Bit during command execution (i.e., while the ID Busy Flag
is ON). It will be ignored.
• Execute the IORD instruction after the Normal End Flag turns ON.
