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.
? Speed-controlled axis for controlling a drive with
speed specification
? Positioning axis for position-controlled posdrive
? Synchronous axis to interconnect with a master
value. The axis is synchronized to the master axis
position.
? External encoder for detecting the actual position of
an encoder and its use as a master value for synchronous
operation
? Cams, cam track for position-dependent generation of
switching signals
? Measuring input for fast, accurate and eventdependent
sensing of actual positions
You program the technology objects with Motion Control
instructions according to PLCopen.he technology CPUs of the SIMATIC also
support extended Motion Control functions:
? Advanced synchronization functions
– Synchronization with specification of the synchronous
position
– Actual value coupling
– Shifting of the master value at following axis
– Camming
? Cam
? Up to 4 encoders or measuring systems as actual
position for position control
? Controlling of kinematics, such as
– Cartesian portals

Roller pickers
– Delta pickers
– SCARA

The following figure shows the connection elements on the rear of the CPU 1511T-1 PN.

You use the mode switches to set the operating mode of the CPU. The following table shows the meaning of the corresponding operation of the operating mode buttons.
