Setting parameters for blocks
3.5 Programming the Ident profile
Ident profile and Ident blocks, standard function for Ident systems

Ending the Repeat command with "SRESET":
1. Reset the "RPTCMD" input parameter and set the "SRESET" input parameter. ①
2. The "DONE" output parameter is set and the reader resets the "RPTACT" output
parameter.

Permanent command repetition can lead to the data being transferred more slowly to the
Ident profile than new transponders are processed. In this case, the reader buffers the
results. The reader has a number of buffers for this. If the buffers are full, no new data is
fetched by the Ident profile; in other words newly arriving transponders are no longer
processed.

233 bytes × 150 = 34 950 bytes

Note
Restriction of command repetition
In the case of RFID systems with unique tag IDs (UID or EPC
U), the stored command is only repeated when different transponders enter the
antenna field. If the same transponder (identical
UID / EPC-ID) enters the antenna field
again and again, the transponder will not be processed again.
