Receive-block

To receive CAN-messages specified in the setup-block, a SIMULINK-model can

contain as many as needed receive-blocks.

The first dialogue-entry specifies from which CAN-port the CAN-message

should be received.

The second dialogue-entry specifies the identifiers for CAN-messages to be

received. The identifiers entered here as a row-vector have to be a subset of the

receive identifiers defined in the setup-block of either CAN-port 1 or 2. If the

an identifier is specified which was not defined in the setup-block an according

error message is output after downloading the xPC Target application. The

block has as many outputs as the row-vector has elements. The data (double /

8byte) received with the identifier as the first element of the is output on the

first block output and so on

The third dialogue-field specifies at which sample time intervals the

CAN-messages have to be read out of the object buffer. By using more than one

receive-block it is possible to get CAN-messages at different sample time

intervals even with the same identifiers by entering appropriate sample times

for each receive-block.
