14 Block Reference
14-38
Specify the length of your CAN message from 0 to 8 bytes. If you are using CANdb
specified signals for your output data, the CANdb file defines the length of
your message. If not, this field defaults to 8. This option is available if you choose to
output raw data or manually specify signals.
Signals Table
This table appears if you choose to specify signals manually or define signals using a
CANdb file.
If you are using a CANdb file, the data in the file populates this table automatically
and you cannot edit the fields. To edit signal information, switch to manually specified
signals.
If you have selected to specify signals manually, create your signals manually in this
table. Each signal you create has the following values:
Name
Specify a descriptive name for your signal. The Simulink block in your model displays
this name. The default is Signal [row number].
Start bit
Specify the start bit of the data. The start bit is the least significant bit counted from
the start of the message. The start bit must be an integer from 0 through 63.
Length (bits)
Specify the number of bits the signal occupies in the message. The length must be an
integer from 1 through 64.
Byte order
Select either of the following options:
• LE: Where the byte order is in little-endian format (Intel). In this format you
count bits from the start, which is the least significant bit, to the most significant
bit, which has the highest bit index. For example, if you pack one byte of data
in little-endian format, with the start bit at 20, the data bit table resembles this
figure.
