f a network. Evaluations, diagnostics, and modifications
are thus possible over long distances. Monitoring and

The trace record can also be displayed through the Web
serverWith OPC UA, you can exchange data via an open and
manufacturer-neutral communication protocol. The CPU
can act as an OPC UA DA server. The CPU acting as the
OPC UA server can communicate with OPC UA clients.
The OPC UA Companion Specification allows methods
to be specified uniformly and independently of the
manufacturer. Using these specified methods, you can
easily integrate devices from various manufacturers into
your plants and production processesYou can use configuration control to operate different
real hardware configurations with a configured maximum
configuration of the hardware. This means that, in series
machine manufacturing in particular, you have the option
of operating/configuring different configuration variants of
a machine with a single project.
RT prioritizes PROFINET IO telegrams over standard
telegrams. This ensures the required determinism in the
automation technology. In this process the data is transferred
via prioritized Ethernet telegramsA reserved bandwidth within the send clock is available
for IRT data. The reserved bandwidth ensures that the
IRT data can be transmitted in time-synchronized intervals,
unaffected by other high network loading
(e.g. TCP/ communication or additional real time communication).
Update times with maximum determinism
can be realized through IRT. Isochronous
applications are possible with IRT.The Isochronous mode system property acquires measured
values and process data and processes the signals
in a fixed system clock. Isochronous mode thus contributes
to high control quality and hence to greater manufacturing
precision. Isochronous mode reduces possible
fluctuations of the process reaction times to a minimum.
Time-assured processing makes higher machine cycles
possible.
MRP
(Media Redundancy
Protocol)
It is possible to establish redundant networks via the
Media Redundancy Protocol. Redundant transmission
links (ring topology) ensure that an alternative communication
path is made available if a transmission link fails.
The PROFINET devices that are part of this redundant
network form an MRP domain.
RT operation is possible with the use of MRP.
MRPD
(Media Redundancy
with Planned Duplication)
The advantage of the MRP extension MRPD is that, in
the event of a failure of a device or a line in the ring, all
other devices continue to be supplied with IO data
without interruption and with short update times.
MRPD is based on IRT and MRP. To realize media
redundancy with short update times, the PROFINET
devices particating in the ring send their data in both
directions. The devices receive this data at both ring
ports so that there is no reconfiguration time.
Shared device The "Shared device" function allows you to divide the
modules or submodules of an IO device up among different
IO controllers. Numerous IO controllers are often
used in larger or widely distributed systems. Without the
"Shared device" function, each I/O module of an IO
device is assigned to the same IO controller. If sensors
that are physically close to each other must provide data
to different IO controllers, several
IO devices are required. The "Shared device" function
allows the modules or submodules of an IO device to be
divided up among different IO controllers, thus
allowing flexible automation concepts. You can,
for example, combine I/O modules that are physically
close to each other in one IO device. PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordination
during pause times regardless of the manufacturer or
device type. Through this, the process should only be
provided with the energy that is absolutely required. The
majority of the energy is saved by the process; the
PROFINET device itself only contributes a few watts of
savings potential.All CPUs support the Motion Control functions
via the technology objects speed axes, positioning axes,
synchronized axes, external encoders, cams, cam tracks
and measuring inputs.
