Basics Profibus

Profibus is an international standard applicable to an open field bus for
building, manufacturing and process automation. Profibus defines the
technical and functional characteristics of a serial field bus system that can
be used to create a low (sensor-/actuator level) or medium (process level)
performance network of programmable logic controllers.
Together with other field bus systems, Profibus has been standardized in

IEC 61158

since 1999.

IEC 61158

bears the title "Digital data com-

munication for measurement and control - Field bus for use in industrial
control systems".
Profibus comprises an assortment of compatible versions. The following
details refer to Profibus DP.

Profibus DP-V0

(

P

)

provides the basic functionality

of DP, including cycle data exchange as well as station diagnostic, module
diagnostic and channel-specific diagnostic.
Profibus DP is a special protocol intended mainly for automation tasks in a
manufacturing environment. DP is very fast, offers plug'n'play facilities and
provides a cost-effective alternative to parallel cabling between PLC and
remote I/O. Profibus DP was designed for high-speed cyclical data commu-
nication between bus master and slave systems.

The original version, designed DP-V0, has been expanded to include
version DP-V1, offering acyclic data exchange between master and slave.

DP-V1

contains enhancements geared towards process automation, in

particular acyclic data communication for parameter assignment, operation,
visualization and alarm handling of intelligent field devices, parallel to cycle
user data communication. This permits online access to station using
engineering tools. In addition, DP-V1 defines alarms. Examples for
different types of alarms are status alarm, update alarm and a manu-
facturer-specific alarm.
Please note in operating the DP V1 functionality that your DP master
supports DP-V1 as well. For this you find details in the documentation to
your DP master.
