The Producer (Producer Tag) sends data at intervals of RPI that is set in the Consumer Tag.
In "Trigger" of the Consumer Tag, "Cyclic" or "Application Trigger" can be selected for

POINT
For Class1 Tag communication, the transmission interval of Producer (Producer
Tag) is set on the Consumer (Consumer Tag) side.
(a) Cyclic (cyclic communication)
Use this to send data only at RPI intervals.
Enter a value for "Requested Packet Interval (RPI)".
Figure 4.4 Cyclic (cyclic communication) setting
(b) Application Trigger (communication at any specified timing)
Use this to allow data communication at any specified timing during
communication at RPI.
Example: On the system with a long RPI setting, communication can be
performed temporarily at shorter intervals.
Communication can be performed at the timing that the Application Trigger
request (Class1)(Un\G27008 to Un\G27023) is set to on.
If no Application Trigger communication has performed for a period longer than
RPI, the communication interval will return to RPI.
Select "Cyclic" for "Trigger".
Consumer Tag
Enter a value for
"Requested Packet
Interval (RPI)".
Select the "Application
Trigger" for "Trigger".
