For the "Getting Started" sample
project, select CPU 314. The example
has been created in such a way that
you can actually select the CPU you
have been supplied with at any time.
The default setting for the MPI address
is 2.
Click Next to confirm the settings and
move to the next dialog box.
Every CPU has certain
properties; for example,
regarding its memory
configuration or address
areas. This is why you have
to select the CPU before you
start programming.
The MPI address (multipoint
interface) is required in order
for your CPU to communicate
with your programming device
or PC.
Select the organization block OB1 (if
this is not already selected).
Select one of the programming
languages: Ladder Logic (LAD),
Statement List (STL), or Function
Block Diagram (FBD).
Confirm your settings with Next.
OB1 represents the highest
programming level and organizes the
other blocks in the S7 program.
You can change the programming
language again at a later date.
