ACKNOWLEDGMENT
I am grateful to Dr.Sudheer Reddy, Head of the department, Mechanical
engineering for his invaluable guidance and support.
I would like to express my great appreciation to Mr. Prashant N for his
valuable and constructive suggestion during the planning and developing
of the case study. His willingness to give his time so generously has been
very much appreciative.
INTRODUCTION
Product selection tools were some of the first apps to go mobile. Bosch
Rexroth (www.boschrexroth.com) and Schneider Electric are two of many
automation suppliers that enable mobile access to searchable product
catalogs, multimedia product information and links to make purchasing
easier.
Another category of industrial mobile app is product configurators and
programming tools. These digitize and streamline the startup and
maintenance of drives, controllers and other components, and securely
store parameters in the cloud for retrieval at any time.

SOLUTIONS
Apps for iOS and Android
To control this triaxial system, Glaub uses a control and diagnostics app
for iOS and Android in order to obtain initial experience and get to know
more about how the technology functions.
CEO Niko Glaub is enthusiastic about the options. “With its Open Core
Engineering concept, Bosch Rexroth is setting something significant in
motion.
It is assuming a leadership role when merging the world of manufacturing
with the IT infrastructure used in offices. It is unleashing all the
advantages we know today in the control of mobile devices.”
Simple programming
Direct access to the control functions and to the variables in the PLC is
implemented by Glaub with the help of three high-level languages: C++,
Objective-C and Java. “Now I can shift complex logic away from the PLC.
This is a great help, since some programming in high-level languages is
far simpler than using the ladder diagram, instruction list or structured
text,” Matthias Fleischer explains.
In addition to machine movements controlled by the accelerometers
integrated into the smart device, the user can also control the system of
axes with gestures executed on the touch screen. There is also a
diagnosis button in the header for the app.

An exciting future
A bridge between automation and the IT world
How industry 4.0 is better than 3.0
In Industry 3.0, we automate processes using logic processors and
information technology. These processes often operate largely without
human interference, but there is still a human aspect behind it. Where
Industry 4.0 comes in is with the availability and use of vast quantities of
data on the production floor.
For an example of the old way (Industry 3.0), take a CNC machine: while
largely automated, it still needs input from a human controller. The
process is automated based on human input, not by data. Under Industry
4.0, that same CNC machine would not only be able to follow set
programming parameters, but also use data to streamline production
processes.
DISCUSSION
Bosch Rexroth is one of the leading specialists in the field of drive and
control technologies. We develop innovative concepts for machine and
plant manufacturers all over the world. With its long history and unique
industry expertise, the company has become synonymous with tailored
solutions. Below is a brief history of Bosch Rexroth, spanning more than
200 years.
In the Factory of the Future everything is connected from field level to
cloud-based IT systems. Automation solutions fit into this environment
only with open standards. They must be easy to (re)configure and
encompass predefined app-based functions. At the same time they must
enable the highest degree of freedom and flexibility to adapt to the
individual needs of businesses.
