Basics
PROFIBUS is an int ernational standard applicable to an open fieldbus for
building, manufacturing and pr ocess automation. PROFIBUS defines the
technical and functional characteristics of a serial fieldbus 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 fieldbus systems, Profibus has been st andardized in
IEC 61158
since 1999.
IEC 61158
bears the title "Digital data com-
munication for measurement and control - Fieldbus f or use in indust rial
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 station
diagnostic, module diagnostic and channel-related 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 data commu-
nication on the sensor-actuator level.
The original version, designed DP-V0, has been ex panded 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 int errupt 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 interrupts. Examples for
different types of interrupts are status interrupt, update interrupt and a
manufacturer-specific interrupt.
If you’d like to use the DP-V1 functionality you have to make sure your DP
master also supports DP-V1. More detailed information about this is to be
found in the documentation of your DP master.
