General information
Machines which use bus lengths of more than 100 meters are often equipped with
INTERBUS or PROFIBUS-DP (PROFIBUS Decentralised Deripherals). The PROFIBUS-DP is
always used together with a master control (PLC).
Here, a PROFIBUS master transfers, for instance, the setpoints to the single PROFIBUS
nodes (e.g. Lenze controllers).
The process data is transferred to the sensors and actuators at the baud rate typical for the
PROFIBUS-DP of 1.5 Mbit/s. Because of the data transfer method and a telegram overhead,
the bus cycle time at 1.5 Mbit/s is high enough to control, for instance, conveyors.
If the process data must reach sensors and actuators more quickly, the PROFIBUS can also
be operated at a baud rate of max. 12 Mbit/s.
PROFIBUS is defined by the PROFIBUS user organisation.
Tip!
Detailed information on the PROFIBUS can be found on the website of the
PROFIBUS user organisation that also develops the PROFIBUS communication
technology:
