What is PROFIBUS-PA?
PROFIBUS-PA is the communication-compatible enhancement of PROFIBUS-DP
with transmission technology suitable for applications in potentially explosive
areas. The transmission system of PROFIBUS-PA meets the international
standard IEC 61784-1:2002 Ed1 CP 3/2.
With the PROFIBUS-PA bus system, the measuring transducer and actuators in
the potentially explosive area can communicate over long distances with the
programmable logic controller. With PROFIBUS-PA, the field devices can be fed
simultaneously via the data line.
The following components are available for the transmission transition from
PROFIBUS-DP (IEC 61784-1:2002 Ed1 CP 3/1) to PROFIBUS-PA
(IEC 61784-1:2002 Ed1 CP 3/2):
