Start-up
D101925 0412 - BLident® UHF 3-20
3.2.5 Multiple access (multitag detection, bulk reading)
The Inventory command is used to request all the currently accessible UIIs within the radio field (see
manuals D101640 - Start-up with CoDeSys for programmable gateways", D101579 - Start-up with
PROFIBUS-DP and D101648 - Start-up with PROFINET").
Note
With the Inventory command, all UIIs of the accessible data carriers in the BLxx-2RFID-A
electronic module are collected within an automatically self-adjusting time window (e.g.
max. 4 seconds for TN865...) and not sent to the gateway until after the command is
executed. The PIB does not allow a partial indication of UIIs.
A command is completed if the following wait time is exceeded after the last collected data
carrier is detected:
250 ms for TN....Q150L170-V1147
350 ms for TN...Q240L280-H1147
250 ms for TN...-Q280 L640-H1147
