Communication PROFIBUS-PA

5.2.1

System architecture PROFIBUS-PA

®
PROFIBUS-PA is an open fieldbus standard to IEC 61784-1 and IEC 61158-2, that has been spe-
cially designed to the requirements of the process industries.
Fig. 5.2: System architecture for PROFIBUS-PA
®
®
In the simplest case the complete
measurement system consists of a
temperature head transmitter, a seg-
ment coupler, a PROFIBUS-PA
mination resistance, a PLC or a PC
with an operation software, e.g. Com-
muwin II.
The maximum number of transmit-
ters per bus segment is dependent on
the current consumption of each
transmitter, the maximum power of
the segment coupler and the required
bus length, see BA198F/00/en.
