Description
DATA
Any / Variant
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.

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
Take inventories for a specified period of time
–
Number of inventories
Take a specified number of inventories
–
Number of "observed" events
Take inventories until a specified number of transponders have been identified at the
same time.
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
