1 Float to Integer, Float Scale 1 3, 4 The Float to Integer conversion changes floating point data to an integer for
transmission to the host. The number of the Convert Code specifies which
floating point scaling value is to be used for the conversion
2 Float to Integer, Float Scale 2 3, 4
3 Float to Integer, Float Scale 3 3, 4
4 Float to Integer, Float Scale 4 3, 4
5 Float to Integer, Float Scale 5 3, 4
6 Float to Integer, Float Scale 6 3, 4
7 Float to Integer, Float Scale 7 3, 4
8 Float to Integer, Float Scale 8 3, 4
9 to 16 No Conversion 6, 16 –
17 Integer to Float, Float Scale 1 6, 16 The Integer to Float conversion changes a transmitted integer value to a
floating point value. The number of the Convert Code specifies which floating
point scaling value is to be used for the conversion. If no fractional part is
coming through on conversion from integer to float, use a float conversion that
more closely fits the range of integer to be converted, such as float range 0 to
10 instead of 0 to 1000.

33 Character to Integer 3, 4 The Character to Integer conversion changes a character data type to an
integer for transmitter to the host.
34 Integer to Character 6, 16 The Integer to Character conversion changes a transmitted integer value to a
character data type.
35 Long to Integer 3, 4 The Long to Integer conversion changes a long data type to an integer for
transmission to the host.
36 Integer to Long 6, 16 The Integer to Long conversion changes a transmitter integer value to a long
data type.
39 Float to Integer, No Scaling 3, 4 The Float to Integer conversion changes a floating point data type to an
integer for transmitter to the host.

transmission to the host.
42 Byte to Float, No Scaling 3, 4, 6, 16 The Byte to Float conversion changes a transmitted byte value to a floating
point data type
43 Float to Long, No Scaling 3, 4 The Float to Long conversion changes a floating point data type to a Long

floating point data type.
45 Float to Byte 6, 16 he Float to Byte Unsigned Character conversion changes a transmitted
floating point value to an unsigned character data type.
46 Float to Unsigned Integer 6, 16 The Float to Unsigned Integer conversion changes a transmitted floating point
value to an unsigned integer data type.
47 Float to Unsigned Long 6, 16 The Float to Unsigned Long conversion changes a transmitted floating point
value to an unsigned long data type.
