The PROFIBUS (Process Field Bus)
is an open communications system for automation engineering
S
is the world's leading field bus
S
is specified in the European standard EN 50170.

The PROFIBUS PA (PA = Process Automation) is a variant of the
PROFIBUS DP (DP = Decentral Periphery) which is widely used in
production technology. The PROFIBUS PA has special transmission
technology with which it is able to meet process automation and
materials processing requirements. This transmission technology is
defined in the international standard IEC 1158--2. The low transmission
speed reduces the power loss and hence enables an intrinsically safe
technology for use in hazardous areas. In addition, the bus topology is
largely freely selectable so that linear, star and tree structures as well
as mixed forms of these are possible. All kinds of field devices such as
transmitters, actuators, analyzers, etc. can be connected to the
PROFIBUS PA. The main advantages of SIPAN analyzers are the
saving of installation costs
S
possibility of further diagnosis with increased availability of system
