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 RF18xC and RF61xR/RF68xR devic-
es, we recommend a memory size of 4 KB. If
you use advanced reader configurations (filter-
ing) 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.
Version identifier (4 bytes)
Based on the identifier, you can uniquely identify
the configuration. This is a time stamp in Linux
format.
The time stamp indicates how many seconds
have passed since January 1, 1979, 00:00 (mid-
night). The identifier is assigned when a configu-
ration is generated.
