24) Data Size: The data size (class=66, instance=1, attribute=10) is settable only if
the Data Type (class=66, instance=1, attribute=9) is Short-String.
25) Width: This attribute is not applicable for Short-String data type. When Width
value (bytes) is set greater than the size (bytes) of the converted value, the Tx
Leading Zeros (class=66, instance=1, attribute=11) bit will pad 0’s in front of the
data (see examples below).
26) Precision: (class=66, instance=1, attribute=12) Specifies the number of places
after the decimal point that are transmitted. This attribute applies only to the Real
data type. The maximum number of decimal points is six (6).
27) Conversion: (class=66, instance=1, attribute=13) Bits 1~5 are unused. When bit
0 is set to 1, the transmitted integer value will be converted to hexadecimal. When
bit 0 is set to 0, the transmitted integer value will be converted to decimal. Bit 7 is
set to 1 to enable Leading Zeros. When Leading Zero is enabled, the zeros are
padded in front of the data.
