Floating point values
Measurement values, setpoints and some parameters are in the INTECONT
®
Satus as
floating point numbers in IEEE-754 4-Byte format. A conversion can be made into another
floating point format depending on the parameter and protocol. Further information can be
found in the protocol descriptions.
The transfer begins at the same time as the MSB.
Here is an example of the transfer of the values 150,5 in IEEE format (the sequence in the
circuit is given):
Byte 1:
Sign/Exponent
Byte 2:
Mantissa 1
Byte 3:
Mantissa 2
Byte 4:
Mantissa 3
0x43 0x16 0x80 0x00
Example of floating point numbers
Number IEEE Format (HEX) Siemens KG-Format (HEX)
1.0 3F800000 01400000
10.0 41200000 04500000
100.0 42C80000 07640000
1000.0 447A0000 0A7D0000
Data(double)words
Data words are transferred in motorola format as standard (high byte followed by a low
byte).
A different byte sequence can be set depending on the protocol and parameters. Further
information can be found in the protocol descriptions.
Byte sequence
Data Type MSB LSB
Int 32 / LONG MSB LSB
Int 16 0 0 MSB LSB
Bit informations
Bits are summed up in words (Modbus, Modbus/TCP) or double words (Profibus, DeviceNet
and Ethernet/IP). The sequence is as follows:
Ex.: Command-ID 0x0140 Komm4_HI Komm4_LO Komm5_HI Komm5_LO
Ex.: Status-ID 0x02F0 Status2_HI Status2_LO Status3_HI Status3_LO
