anufacturing precision. Isochronous mode reduces
possible fluctuations of the process reaction times to a
minimum. Time-assured processing makes higher
machine cycles possible.
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 he 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 participating 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.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.The advantage of the MRP extension MRPD is that, in

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. CPUs support the controlled positioning and
traveling of axes via Motion Control functions
by means of the following technology objects:
Speed-controlled axes, positioning axes, synchronized
axes, external encoders, cams, cam tracks and measuring
