plement) or 0 to 255. Floating values are always interpreted as signed. Bit-
values make no distinction between signed and unsigned.
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 art position in data.
l
Encoding type
Displays the encoding type used for interpreting the transmitted payload
data.
Binary (the received bytes are interpreted as binary data), ASCII
(ASCII characters, i.e. text) or ASCIIHex (the received ASCII characters are
interpreted as hexadecimals pairs). The data is converted into the given data
type after being received.
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.

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
If the sent values require conversion, enable Scaling and enter Min / Max values to
convert from the Measurement value into the Scale value .
Without scaling, the channel's Data type is used When scaling is
enabled, the floating data type is always used for the channel.
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 num-
ber).
