SIMIT – Simulation platform for virtual commissioning

Overview
SIMIT for simulating new machines during development
SIMIT allows you to simulate the interaction between your ma-
chine tool or production machine and your automation system at
all stages of product development, from commissioning through
to sales and after-sales.
Long before you finish developing a machine and building a
prototype, you can simulate its performance using SIMIT. For this
purpose, the automation system is simply coupled with a virtual
behavioral model of the machine. This coupling has been
optimized for high-performance machine tools and production
machines with state-of-the-art control technology from Siemens
such as SINUMERIK and SIMATIC.
Your automation system – fully integrated
SIMIT is a simulation system that supports a wide range of
hardware and software interfaces to the automation system:
PROFIBUS, PROFINET, PRODAVE, PLCSIM, OPC, and Shared
Memory. If you want to connect the entire Control Unit, e.g. in-
cluding the CNC, PLC and the Human Machine Interface to a
machine model in SIMIT, you can simply use a hardware inter-
face for PROFIBUS. The axis values of the CNC are transferred
to the PLC using the software option SINUMERIK Integrate for
engineering Run MyCC /ADAS and thus become visible for
SIMIT. SIMIT provides consistent support for the exchange of
data with the engineering environment of your automation sys-
tem.
The 2-channel interface module IM-PBDP-2 simulates
PROFIBUS DP standard slaves and SIMATIC S7
slaves, including fail-safe SIMATIC slaves. Up to 125 DP slaves
in a DP master system can be simulated per channel. The inter-
face module is connected to the PC via Ethernet.

Overview
(continued)
SIMIT makes simulation as simple as it can be
Even though computer simulation is often regarded as a highly
complex process, you do not need to be a simulation specialist
to work effectively with SIMIT. All you need to do is operate the
ergonomically designed, graphical user interface of SIMIT, while
the application itself processes all mathematical and IT proce-
dures associated with the simulation invisibly in the background.
Furthermore, a 3D VRML Viewer (integrated in SIMIT) permits
simple visualization of machines and plants.
In addition, the shared-memory interface SIMIT Ultimate can also
be connected to tools such as the Siemens PLM Mechatronics
Concept Designer – for extensive 3-D physical simulation.
SIMIT – modeling the machine
Based on a modular principle, the simulation model of the ma-
chine is created on the SIMIT graphical user interface by the
joining together of individual components and Control Units.
Simulation elements are simply dragged from the library and
dropped into the machine model. The extensive basic library
supplied with SIMIT provides you not only with standard arithme-
tic and logic functions, but also blocks for interfacing a broad
range of I/Os of your automation system.
Using SIMIT's component type editor, you can create completely
new types of component and use them in your simulations. You
can freely define the connections and states of these component
types as well as the functional and graphical response, allowing
you to work extremely efficiently even when your machine
models are complex.

Benefits
7
SIMIT combines savings in time and cost with enhanced
product quality in machine tool and production machine build-
ing. SIMIT supports you during key phases of the develop-
ment of machine tool and production machine products:
development, commissioning, testing, and service.
7
The automation solution used, including all of the software
modules developed by the machine manufacturer, can be
tested with SIMIT in advance and in a reproducible manner –
all without having the real "steel and iron" version of the ma-
chine at hand.
7
A new machine can be tested without being subjected to any
risk since proper functioning is checked in virtual reality. After
the development work on the new machine has been com-
pleted, the virtual machine that has been generated can also
be used for training, pre-sales and after-sales purposes.
