Description
It is possible to establish redundant networks via the
Media Redundancy Protocol. Redundant transmission
links (ring topology) ensure that an alternative commu­
nication path is made available if a transmission link fails.
The PROFINET devices that are part of this redundant net­
work form an MRP domain.
RT operation is possible with the use of MRP.
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 redund­
ancy with short update times, the PROFINET devices par­
ticipating 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 differ­
ent 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 mod­
ules 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 coordina­
tion 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.
S7-1500 CPUs support the controlled positioning and
traveling of axes via S7-1500 Motion Control functions
by means of the following technology objects:
Speed-controlled axes, positioning axes, synchronized
axes, external encoders, cams, cam tracks and measuring
inputs.
• Speed-controlled axis for controlling a drive with
speed specification
• Positioning axis for position-controlled positioning of
a drive
• Synchronous axis to interconnect with a master
value. The axis is synchronized to the master axis pos­
ition.
