Introduction
This guide takes you through 6 commissioning steps to set up a functioning appli-
cation by running through a concrete example. In this way you will get to know the
basic hardware and software functions of your CPU 31xC.
You should expect to spend approximately 1.5 to 2 hours on this example, depen-
ding on the level of your experience.
Prerequisites
The following prerequisites must be fulfilled:
S You must be familiar with the fundamentals of electronic/electrical engineering
and have experience of working with computers and Microsoft Win-
dows
