5-2 Control Procedures for Each Communication
In Write Command (WT) with UID/SNR addition setting disabled (in I.CODE1 Mode, the command with
UID/SNR addition setting eabled is also covered),
the Reader/Writer communicates with all the Tags in the communication area on receiving the command,
and returns the results of the communications with each tag as a response. At the completion of
communicating with all the Tags, it returns Detection End Response (Response Code: 00) once.
The number of Tags with which the communication has been normally completed is added to Detection
End Response. When no Tag is present in the communication area, it returns Detection End Response
(Response Code: 72).

Multi-Trigger Command (WT)
マルチ・トリガ・コマンド（WT）
In ISO Mode, if the communication with the detected Tag failed, the Reader/Writer returns an error
response immediately and moves on to process another Tag. At the completion of communicating with all
the detected Tags, it returns the Detection End Response and terminates the command processing.
In I.CODE1 Mode, the Response Code is set to 00 only after the communications with all the detected Tags
have been completed successfully. When the number of Tags detected exceeds the number specified by the
Tag code in command data, the Response Code is replaced with a warning code (Code: 0□), (Refer to
SECTION
If data writing process in even one Tag has failed, the Reader/Writer returns to Write Process Error
(Response code: 71), and terminates the command processing.
In processing Multi-Trigger Command, some Tags may not be processed due to their conditions (including the
distances between the antenna and Tag, or those between the Tag and another Tag). The operating system must
be configured to check the number of processed Tags based on the number of returned responses or normally
processed Tags, and match them against the actual number of the Tags.
