This CAN bus record structure is needed when receiving (sampling).
uint64 MXF_CANBUS_SAMPREC::timeTag |
Specifies the time when the data record has been received by the device. It is an absolute time expressed on the time base set for the device. The time tag may also be disabled with the KMXF_CANBUS_RX_TIMETAG_ENABLE attribute.
uint32 MXF_CANBUS_SAMPREC::control |
For receive operation, the control field defines the condition under which the related record data was received.
The control bits are defined as follow:

A control of zero indicates that no errors was found while receiving data.
uint32 rate; /**< Time between the reception of the last two records expressed in the resolution of the process time base (usec or nsec). The maximum is about 1 sec; 4000000 in nsec or 4000 seconds in usec. If time tag is disabled, the rate will always be set to 0.
