Benefits of Model-Based Design
Increased Revenueby creating products that could not have
been
developed otherwise
“In the past, it was prohibitively
expensive to build the necessary
controller hardware for
specialized products. With
Simulink, we can easily implement
our controller designs on our
existing PLC hardware. [We can
now] pursue new business
opportunities for engineering
low-volume controller products”

Benefits of Model-Based Design
Reduced Development Costby reusing models and adapting
designs
“After implementing the PLC
version with Simulink PLC
Coder, with a few
modifications we generated
the microprocessor code using
Embedded Coder. We switched
from a structured text
implementation to C, just by
changing the code generation
product.”
