Message Objects
Fault Confinement
Overload Frame
Number of MObs
Notes:
(c.f.
An overload frame is sent by setting an overload request (OVRQ). After the next reception, the
CAN channel sends an overload frame in accordance with the CAN specification. A status or
flag is set (OVRG) as long as the overload frame is sent.
Figure 19-9. Overload Frame
The MOb is a CAN frame descriptor. It contains all information to handle a CAN frame. This
means that a MOb has been outlined to allow to describe a CAN message like an object. The set
of MObs is the front end part of the “mailbox” where the messages to send and/or to receive are
pre-defined as well as possible to decrease the work load of the software.
The MObs are independent but priority is given to the lower one in case of multi matching. The
operating modes are:
This device has 15 MObs, they are numbered from 0 up to 14 (i=14, no MOb 15).
