Description
The MRP interconnection process is an enhancement of
MRP and allows the redundant coupling of two or more
rings with MRP in PROFINET networks. MRP intercon-
nection is - like MRP - specified in the IEC 62439-2
standard (Edition 3).
The "Shared device" function allows you to distribute
the modules or submodules of an IO device to 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. Therefore,
if sensors close in distance to one another have to sup-
ply data to different IO controllers, several IO devices
are required. The "Shared device" function allows you to
distribute the modules or submodules of an IO device to
different IO controllers, thus allowing flexible automa-
tion concepts. You can, for example, combine I/O mod-
ules lying near one other in one IO device.
PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordi-
nation during pause times regardless of the manufac-
turer 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 measur-
ing 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 follows the synchronous operation
of the position of the leading axis
• External encoder for detecting the actual position of
an encoder and its use as a master value for syn-
chronous operation
• Cams, cam track for position-dependent generation
of switching signals
• Measuring input for fast, accurate and event-
dependent sensing of actual positions
• PID Compact (continuous PID controller)
• PID 3Step (step controller for integrating actuators)
• PID Temp (temperature controller for heating and
cooling with two separate actuators)
