Parameter Records (Index 0x2000 – 0x2FFF)
8.6.5.1
General
It is possible to parameterize the sensor via the records 0x2000 to 0x2FFF.
The read/write request is addressed as follows:

n bytes
0x2000 records are divided into subobjects. Each subobject is uniquely identified by a subindex. The reading of a 0x2000 record is
always done from the beginning starting with subindex 0. All subobjects of a 0x2000 record are readable. A smaller part of a 0x2000
record is writable. For this purpose an additional header is coded into the user data of the write request, which makes it possible to
address a single subindex within a 0x2000 record:
Name

Reading 0x2000 records is done without the header.
