Overview
(continued)
Apart from electrical drives, hydraulic drives within a controller
or distributed over several controllers can be synchronized with
each other. This supports the implementation of integrated
automation solutions such as conveyor systems and press lines
in the automotive industry, in which both electrical drives
(winders, cross cutters, roller feeds) and hydraulic drives (e.g.
deep-drawing presses) are implemented in the same system.
The project generator SIMOTION easyProject enables basic and
modular machine functions to be integrated into SCOUT
engineering projects. The project generator is not currently
available for SCOUT TIA (SIMOTION in the TIA Portal).
SIMOTION isochronous mode
In the SIMOTION system, all the components (one or more
control units, drives, isochronous I/Os) are synchronized to the
communication cycle of the machine, the PROFINET/
PROFIBUS DP cycle. The application is also synchronized with
this cycle through synchronous application tasks (in the servo
and interpolator cycle). Isochronous mode therefore permeates
the whole machine application (also in the case of distributed
systems) and this provides considerable advantages:
•
Short response times from terminal to terminal and terminal to
axis
•
High machine cycle times
•
Programming of synchronous closed-loop control tasks
•
High product quality thanks to a deterministic and
reproducible machine response
Modular concepts – Modular machines
SIMOTION supports modular machine concepts and thus
reduces engineering and commissioning costs through:
•
Modular software development with libraries and reusable
modules,
•
Division into individual machine modules, which are linked, for
example, through distributed synchronous operation (over
PROFINET IO with IRT or PROFIBUS DP).
•
Reconfiguration of a project during runtime, e.g. via HMI.
•
Activation/deactivation of PROFINET IO devices/DP slaves
(I/O components) and technology objects (axes, drives,
external encoders, probes and cams) during engineering and
at runtime.
•
Easy, modular configuration of projects using the project
generator SIMOTION easyProject.
The modular machine concept means that scalable solutions
and large axis line-ups can be achieved. Standardized modules
can be easily adapted to special requirements and separately
tested. These modules are then easily combined to form
individual machine variants.
Communication using Ethernet/PROFINET
The following communication functions are available via
Ethernet/PROFINET on all platforms:
•
I/O communication between SIMOTION and/or SIMATIC
controllers
•
Communication with SIMOTION devices, SIMATIC CPUs and
non-Siemens devices via UDP and TCP/IP
•
Communication with programming devices (programming
device functions)
•
Communication with SIMATIC HMI devices
•
Communication via OPC UA server to clients on any other
devices
•
Communication via the SCADA system WinCC
•
Communication with PCs on which SIMATIC NET OPC is
installed.
A prerequisite on the PC side is the
SIMATIC NET SOFTNET S7 software.
Communication via PROFIBUS
The communication functions are available via PROFIBUS on all
platforms:
•
I/O communication between SIMOTION and/or SIMATIC
controllers
•
Communication with programming devices (programming
device functions)
•
Communication with SIMATIC HMI devices
•
Communication with PCs on which SIMATIC NET OPC is
installed.
A prerequisite on the PC side is the
SIMATIC NET SOFTNET S7 software.
SIMOTION IT
SIMOTION IT enables additional communication functions via
Industrial Ethernet:
•
In-depth service and diagnostic functions without the need for
a project and engineering system via the integrated standard
web pages of SIMOTION IT
•
Diagnostics, commissioning and operation via user-defined
web applications
•
Communication and application access to process values via
OPC XML-DA
•
SIMOTION IT Virtual Machine: Integration of individual Java
applications into the integrated SIMOTION Java runtime
environment, for parallel operation with automation functions.
