10.9.6 CAN_RxMask
14643
Function block type:
Function block (FB)
Behaviour model:
ENABLE
Library:
ifmRawCAN.library
Symbol in CODESYS:
>
Description
14641
The FB receives CAN messages of a non-coherent area. The area is defined by a bit pattern and a bit
mask.
The following rules apply to the bit mask:
 0: The equivalent bit of the CAN identifier can be 0 or 1
 1: The equivalent bit of the CAN identifier must have the same value as the bit in the bit
pattern
Example:
Pattern: 000 0010 0000
Mask: 000 1111 1111
Result: xxx 0010 0000
All CAN messages with an identifier whose 8 least significant bits have the value "0010 0000" are
received.
E.g. 110 0010 0000 000 0010 0000, 001 0010 0000
