Description
Should be a valid description of the mapping which helps understanding its purpose and
context in future.
Mapping Variable Type
CANFreestyle only supports one type:
·
Length based mappings find every variable (or constant) by position and length
within the CAN message. If length based mappings are less than 8 bytes long,
their variables or constants can be placed at any position. If they shall be longer,
the variables and constants have to be byte aligned.
Receive from / Transmit to
For receive mappings: Select the ECU which will send the Mapping where the variable
should be extracted.
For transmit mappings this property describes the destination address to be used (i.e.
the ECU that shall receive the values).
Little Endian/Big Endian
CANFreestyle values are transferred least significant byte first (Little Endian) by default.
Here you can change this to most significant byte first (Big Endian). If you have a
Mapping which contains Little and Big Endian values you have to create two separate
mappings.
This setting only applies to numeric values. Strings are expected to be "big endian" i.e.
the first byte of the word or sentence is the first one on the bus.
Mapping Length
Enter the length of the message you want to configure. The length has to be between 0
and 8 bytes.
Object Status
With Object Status Active the mapping is working, i.e. it is processing received
messages or sending them. With Object Status Inactive the mapping is not working. This
property can be switched at run time with the setProperty JavaScript function to
enable / disable CAN mappings.
CAN ID Type
This setting defines whether an '11 Bit Identifier' or '29 Bit Identifier' should be used for
the CAN ID.
CAN ID (0x)
This defines a CAN ID for the appropriate Mapping. The ID is not unique so it is
possible do define several mappings with the same ID e.g. if a multiplexer is used.
CAN ID Mask
If not all bits of the Identifier should be evaluated it is possible to define a CAN ID Mask
which only evaluate the needed bits of the CAN ID.
NOTE: You can define your own CAN ID Mask here .
