tion. RS 485-IS (Intrinsically Safe) covers uses in
explosion protected areas. The MBP (Manchester
coded Bus Powered) and MBP-IS transmission
technology is specifically oriented toward the pro-
cess industry and also handles power supply to
devices on the bus, in addition to data transmis-
sion. Several optical transmission technologies
are also available.
PROFIBUS application profiles are specified for
standard data exchange between field devices on
the user level. The use of such profiles guaran-
tees interoperability in the data exchange be-
tween field devices from different manufacturers.
These profiles specify application-typical device
features, and "profile devices" must comply with
them. They might be cross-device-class features
(e.g. safety-relevant behavior) or device-class-
specific features (e.g. to be exhibited by process
devices or drives). Field devices with different
application profiles can be operated in the same
automation system. S imple devices with univer-
sal functionality, e.g. decentralized binary I/O de-
vices, do not usually use application profiles.
Additionally to the layers for transmission and
communication, the system building block also
provides the required engineering technologies
for device description and integration.
1.3 Application-specific
solutions
The system building block makes it possible to
cover very different applications using "solutions"
specifically arranged for them by combining the
appropriate components. Examples include
solutions for the production industry, process au-
tomation, drive engineering and s afety-related
systems. The structure of these modular
"solutions" can be seen in Figure 2. Only the
communication protocol is the same with all
solutions and ensures the high consistency of
PROFIBUS already mentioned.

Blast furnaces are operated without inter-
ruption and can only be modernized
at long intervals. This makes especially
future-proof automation technology all the
more important. PROFIBUS has proven
itself through and through in large-scale
