Inventory

The "Inventory" block activates the taking of inventories. There are four different modes that
you can select with the "ATTRIBUTE" parameter.
● At the start, a certain duration/number (period of time, number of inventories, number of
"observed" events or identified transponders) is specified. A distinction is made between
the following options:
– Duration
– Number of inventories
– Number of "observed" events
Inventories are then taken by the reader for this time or number of inventories. When the
specified time/number is reached, the block is ended and returns all identified
transponders in "IDENT_DATA". The transponders are sorted according to the RSSI
value (highest value first). In other words, other commands can only be executed when

Description
Data buffer for configuration data.
The real length of the data depends on the com-
plexity of the configuration and the firmware
version of the reader. With a standard configura-
tion of the RF680R/RF685R reader, we recom-
mend a memory size of 4 KB. If you use
advanced reader configurations (filtering) or
want to change the configuration in the future
without needing to adapt the memory size of
"DATA", we recommend a memory size of 8-16
KB.
Note:
For Variant, currently only an "Array_of_Byte"
with a variable length can be created. For Any,
other data types/UDTs can also be created.
