As packets can only ever be transmitted in byte size on
the CANbus, this CAN message has a data length of 7
bytes.
With the CAN Receive functionality (CAN decoder
<CanInChannel>) in the MX840B, or of another CAN
channel of an MX471B, this CAN message can be
directly decoded again to four different signals, by taking
over <DataFormat>, <StartBit>, <BitSequence> and
<SignalLength> from the above parameterization.

Transmission type
When does transmission take place?
For a CAN message, <TransmissionType> defines when
the message on the CAN bus is to be sent. There are
various modes to choose from. The transmitted value is
always the one actually present at this time. If a value for
a source is not yet known, the value parameterized in
Section 5.5 is transmitted.
