PROEMION CANlink wireless 3000 Series Device Manual page 114

Example 2:
CAN messages with the CAN identifiers 0x123, 0x124, and 0x125 are transmitted. The required
filter mask must be determined using an XNOR gate. Other CAN messages that comply with the
filter mask (e.g. 0x120, 0x121, 0x122, etc.) are also received. CAN messages with other CAN
identifiers are forwarded to the next online CAN object.
Set the filter mask:
Online CAN object
11-bit CAN identifier (hex): 0x123
11-bit CAN identifier (hex): 0x124
11-bit CAN identifier (hex): 0x125
XNOR gate for filter mask
Filter mask 0x7F8 (hex)
