The following values have proven their worth in practice:
u
"0" to "5" for dynamic applications (rapidly passing ID tags)
u
">5” for static applications

Object UID filter depth
The "UID filter depth" object (0x4603/0x00) allows for determining the number of successful ID tag
detections to be executed by the device. The ID tag will only be considered on the CAN bus as having
been detected (ID tag present) once the set number has been reached.
The value "0" deactivates the filter. The values ">0" delay the "ID tag present" bit by 7 ms. Thus a
switch-on delay of the ID tag value is generated. The detection in the limit range stabilises as no value
will be provided as long as the ID tag has not been steadily detected.
Object zero ID filter depth
The "Zero ID filter depth" object (0x4605/0x00) allows for determining the number of unsuccessful ID
tag detections to be executed by the device. The ID tag will no longer be considered on the CAN bus
as present (ID tag present) once the set number has been reached.
The value "0" deactivates the filter. The values ">0" delay the reset of the "ID tag present" bit by 7 ms.
Thus a switch-off delay of the ID tag value is generated. The detection in the limit range stabilises as
no value will be provided as long as the ID tag does not remain steadily undetected.
