Once the filter is activated by checking the
On/Off
box, the CAN input messages will pass
through to the Ethernet network only if their CAN ID is within the range specified by
From
and
To
configuration parameters.

Where:
𝐼𝐷
𝐶𝐴𝑁
– CAN message ID,
𝐹𝑟𝑜𝑚
–
From
configuration parameter,
𝑇𝑜
–
To
configuration parameter.
The
EID
box (
Extended ID
box) defines whether the CAN message ID is regular or extended.
All CAN ID range filters run in parallel. It is sufficient to satisfy requirements of any active filter
to pass the CAN message to the Ethernet network.
If no active filters are defined, it is considered that the CAN ID range filters are disabled, and
do not participate in the message filtering process. In this case,
ID Range Filters
are
Off
on the
home page, and, if other filters are also disabled, all CAN input messages will be sent to the
Ethernet network.
3.3.2 CAN ID Mask Filters
The CAN ID mask filters are set through the
CAN ID Mask Filter
configuration web page.
Figure 13. Converter CAN ID Mask Filters Page
There are five independent CAN ID mask filters:
Filter 1, Filter
2, …, Filter 5
