The variables have a fixed format:
+99999999.999999
While transmitting the variables via the Profibus interface, a signed 32-bit
number (1 Long) with an operational sign, that is interpreted according to
its Format selection, is transmitted. The data capacity of the variable is
reduced. For the two types of fixed point formats, the places after the
decimal are always rounded. For the integer format, only the places
before the decimal are used. The transmission formats must correspond
to the application of the variable in the NC program.
• The following data formats are defined:
0 (0000) = Integer (+/-99999999)
1 (0001) = Fixed point (3) (+/-99999.999)
2 (0010) = Fixed point (6) (+/- 99.999999)
3 (0011) = IEEE Floating point (in preparation)
4 (0100) = Integer, not rounded (+/-99999999)
• When the error bit (Bit 14) is set in the status word, error numbers are
assigned to the format bits (Bits 10-13). The following error numbers
are assigned:
0 (0000) = Variable number too large
1 (0001) = Variable number illegal
2 (0010) = Unknown format
3 (0011) = Data too large
4 (0100) = Data too small
5 (0101) = Data not displayable
6 (0110) = Variable not writable
7 (0111) = Bit 14 in the control word is ‘1’
8 (1000) = Indexed variable number too large
9 (1001) = Indexed variable number too small
