The EPCLengthMin and EPCLengthMax parameters can
be used to define a filter that excludes data carriers during
detection if their EPC length is not within the specified filter
range.
The EPCLengthMax (default) parameter defines the
maximum EPC length in bytes, which is set after switching
on or after a restart of the processor unit.

The EPCLengthMin and EPCLengthMax parameters can
be used to define a filter that excludes data carriers during
detection if their EPC length is not within the specified filter
range.
The EPCLengthMax parameter sets the maximum EPC
length in bytes and overwrites the EPCLengthMax (default)
parameter until the current TCP session is terminated or
the processor unit is restarted.

EPCFilter (default)
Parameter-ID:
UHF-Manager:
OPC UA:
Webserver:
The EPCFilter (default) parameter can be used to create a
specific data filter that selects data carriers directly
according to a predefined filter mask during detection and
reports only those data carriers that match this filter mask.
The default filter is applied after switching on or after
restarting the processor unit.
The filter mask is defined in the following form:
Filter mask = Address [1 word] + length [1 word] + filter
Meaning
data [max. 62 bytes]
EPC minimum
Address and length specifications must be specified in
length for filter
bits. Masks can thus also start and end in the middle of
(default)
bytes.
The value range in each case is 0...496 bits.
The sum of both values must not exceed 496.
The 16-bit values are specified as 2 bytes in the order
Low – High.
The f
that allow the number of bits in the Length field to be
transmitted with it. The bits are to be left-aligned and
padded at the end to a whole byte length with zero bits.
Example:
Only data carriers whose EPC from byte address 02
onwards contains the data E2 00 01 02 03
5 bytes) are to be reported.
