Comment
Select the bit rate on the CAN subnetwork.
Select what will happen to the CAN controller when the CAN
subnetwork goes bus off.
When the Control/Status Word is enabled this parameter will
be disabled (No Action).
Select CAN identifier size on the subnetwork
If there are configured transactions when this parameter is
changed, the following will happen:
• A change from 11 bit to 29 bit identifier will cause the
identifier to be padded with zeroes up to 29 bits, keeping
the 11 bits at the same location.
• A change from 29 bit to 11 bit identifier will cause the
upper 18 bits to be deleted and the lower 11 bits kept.
This may in some cases cause faulty CAN identifiers.
Default = 0 (disabled)
The minimum time that must elapse between the end of a
message and the beginning of the next message. If a device on
the CAN subnetwork is slow and/or does not have a message
queue, it may be necessary to enter a delay between the
messages to ensure that they are handled correctly. The delay
is set in milliseconds.
Disabled: All CAN frames that are not successfully transmitted
will be buffered. The size of the buffer is 255 frames. If the
buffer is full, new frames will be discarded.
Enabled: While the CAN state is Error Passive, all CAN frames
that are not successfully transmitted will be discarded.
The usual reason for Error Passive state is disconnection of the
CAN cable.
