• Timing Chart (CIO n = CIO 2000 + (10 x 0) = CIO 2000)
• If communications with the RF Tag fail or an error occurs, communications will be aborted at that
point, the error flags 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.
• If the Abort Bit is turned ON while waiting for an RF Tag, communications will be aborted at that point.
The Results Information (CIO n+8) will always be 0000 hex in this case.
• To confirm the execution results from the user program, use the ON status of the Normal End Flag or
Error End Flag in 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.
