To open this library, type

The FIFO Read RCV Level driver block reads the current number of CAN messages stored in the receive FIFO. The receive FIFO can store up to 127 events (messages). If it is full and a FIFO Read driver block does not attempt to read the stored messages, the driver ignores new incoming messages. Increments to the lost message counter show the number of lost messages. You can use this driver block to check for this condition and perform an error action, such as stopping the execution or resetting the receive FIFO.
The block has a single output port of type double, returning a scalar value containing the current receive FIFO level (number of messages to be processed).
Defines the board accessed to read the current receive FIFO level. For more information about the meaning of the board number, see the Setup driver block. If just one board is present in the target system, select board number 1.
Defines the sample time at which the FIFO Read RCV Level driver block is executed during a real-time application run.
