2.4 Creating and Saving a Project
Before you create a program, you must create or open a project. When you create a new
project, STEP 7-Micro/WIN opens the following editors:
S
Ladder Editor or Statement List Editor (depending on your selected preference)
S
Data Block Editor (not applicable for the PDS 210)

Creating a New Project
The Project menu command allows you to create a new project, as shown in Figure 2-4.
Select the menu command Project
"
New.... The CPU Type dialog box is displayed. If you
select the CPU type from the drop-down list box, the software displays only those options
which are available for your CPU. If you select “None,” no CPU-specific restrictions are
placed on your program. When you download the program, the CPU notifies you if you have
used options that are not available. For example, if your program uses an instruction that is
not supported by your CPU, the program is rejected.
Note
STEP 7-Micro/WIN does not range-check parameters. For example, you can enter MW999
as a parameter to a ladder instruction even though it is an invalid parameter. This error
would be identified when you attempt to download the program.
