Basics
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
(Decentralized Peripherals)
provides the basic
functionality of DP, including cycle data exchange as well as diagnostics
functions.
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
communication 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 manufacturer-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.
