CAN-AC2-PCI
16-15
The last 4 dialogue-entries are used to define the Identifiers of all
CAN-messages sent or received within the current SIMULINK-model. There is
one dialogue-field for send- and receive-identifiers for CAN-port 1 and 2. Each
entry can contain a row vector with a maximal number of 200 identifiers. Each
identifier can be in the range of -(2^29)..2031). Because CAN-specification 2.0B
allows to send and receive messages with standard (11bit) and extended
identifiers (29bit) concurrently the following identifier numbering method has
been implemented:
•Positive numbers specify standard identifiers and can therefore be in the
range from 0..2031
•Negative numbers specify extended identifiers. Because the number zero is
reserved for the standard identifier 0 the extended identifier 0 has the
number -1 and the extended identifier 1 the number -2 and so on. Therefore
the standard identifier range 0 to 2^29-1 is mapped to the range
-1..-(2^29).
