l
Bit length
Sets the bit lengths for integer and floating data types.
Byte sequence
and
Word sequence
are adjusted according to length value. This also applies to
the numeric fields in the St
l
Encoding type
Displays the encoding type used for interpreting the transmitted payload
data.
l
Byte sequence
The byte order (byte sequence) is a number, made up of several bytes, that
sets how bytes are ordered for the address. BigEndian, also known as
Motorola format, orders the most significant byte to the lowest address.
LittleEndian, also known as Intel format, orders the least significant byte to
the lowest address. Refer also to
http://en.wikipedia.org/wiki/Endianness.
l
Word order
Like the byte order, word order orders word data (1 word = 2 bytes = 16
bits) to addresses. In addition to determining byte order, a different word
ordering may be necessary.
l
Byte pattern
To display the different byte and word order combinations, a hex value (a ran-
dom number in the example) is shown with the resulting byte pattern of a
message.
Scaling

option is used, scaling takes place in the
opposite direction: Enter the range from the source data in
Scale
value
and the range for the output signal in
Output value
.
Without scaling, the channel's
Data type
is used. When scaling is
enabled, the floating data type is always used for the channel.
This also applies when the channel is used as an output: When scal-
ing is enabled, the channel must have the floating data type, oth-
erwise you have to use the type under Data type.
Scaling example
In the above image, a conversion takes place from 2000 (integer value) to
200 (°C), i.e. it returns a decimal point despite transmission of an integer
(whole number).
Using the channel as output
If you create a CAN bus channel as an output, you can send data from the
