3.1 General information
PROFIBUS-DP is a manufacturer-independent, open fieldbus standard for a wide
range of applications in manufacturing, process and building automation. Manufacturer
independence and openness are ensured by the international standards IEC 61158 and
IEC 61784.
PROFIBUS-DP allows devices from different manufacturers can communicate without
any special interface adaptation. PROFIBUS-DP can be employed for both high-speed
time-critical data transmission and extensive, complex communications tasks.
3.2 PROFIBUS types
Fig. 1: PROFIBUS types
PROFIBUS-DP This PROFIBUS variant, which is optimized for speed and low connection
costs, has been specially tailored for communication between automation control systems
(PLCs) and distributed field devices (typical access time < 10 ms).
PROFIBUS-DP can be used to replace conventional, parallel signal transmission using
24 V or 0(4) to 20 mA signals.
DPV0:Cyclic data transfer:

--> is supported
n DPV1:Cyclic and acyclic data transfer:

n DPV2:In addition to cyclic and acyclic data transfer, slave-to-slave communication
occurs:
--> is not supported
PROFIBUS-PA
PROFIBUS-PA has been specially designed for process engineering and permits the
linking of sensors and actuators to a common bus line, even in potentially explosive
zones. PROFIBUS-PA allows data communication between and supply of power to
devices based on two-wire technology in acc. with MBP (Manchester Bus Powering) as
specified in IEC 61158-2.
PROFIBUS-FMS
This is the universal solution for communication tasks at the cell level (typical access time
approx. 100 ms). The powerful FMS services open up a wide range of applications and
provide a high degree of flexibility.
FMS is also suitable for extensive communication tasks.
