4.3 Data-format description
Floating point :=
[ <sign> ] <digits> ['.' [ <digits> ] ] 'E' [<sign>] <digits>
<sign> := '+' | '-'
<digits> := '0' .. '9' [ <digits> ]
Example:
Floating point := '23.45E-12'
Note: As can be seen in section 4.2 do JVL motor controllers not support exponential no-
tation in connection with real numbers. Format=4 can therefore not be used in connection
with JVL motor controllers. Use instead a suitable fixed point format.
See section 4.3.6 to section 4.3.9 .
4.3.5 Binary
Format = 5.
PROFIBUS format:
Data format: 16 bit
Number range: 0 .. 0xFFFF
RS 232 format:
Data format: ASCII
Number range: '0000000000000000' .. '1111111111111111'
4.3.6 Fixed point * 1.0
Format = 6.
PROFIBUS format:
Data format: 32 bit
Number range: 0x80000000 .. 0x7FFFFFFF
RS 232 format:
Data format: ASCII
Number range: '-2147483648.0' .. '+2147483647.0'
In this fixed point format, the least significant bit in PROFIBUS-data has the value: 1.0.
Example:
PROFIBUS-data RS 232 data
0x401 '1025.0'
