13 Fieldbusses
All protocol variants of the INTECONT® Satus are described in the following chapters. If you
use one of the following protocols, you should always read the chapter ‘Fieldbusses
’ and the
protocol-specific chapter before commissioning!
This chapter describes all the data that can be transmiited via the various Fieldbus
protocols. The data basis is the same for all Fieldbusses. The particulars are described in
the protocol-dependent sections.

Data segments
In the INTECONT® Satus system, a distinction is made between the following cyclical data:
n
Commands (Bit- or Byte information),
n
Setpoints (floating point values),
n
Status information (Bit- or Byte information),
n
Measured values (floating point values),
n
Long (INT32)-values (integer values)
Dimensions
INTECONT® Satus uses two systems of units
n
SI-units and
n
NON SI-units
The parameter ‘Units’ is used to switch between the two.
For the Fieldbusses this means that in the
n
SI setting, all dimensioned magnitudes are transferred in the units ‘m, kg and sec’.
n
If you have chosen NON-SI, the dimensioned magnitudes are transferred in ‘ft, lb and
sec’.
