Configuring the Central Rack
In order to change the parameters (for example, address) of a module within a
project, double-click the module. However, you should only change the
parameters if you are sure you know what effects the changes will have on your
programmable controller.
No changes are necessary for the "Getting Started" project.
You can also check your configuration for errors using the menu command Station >
Consistency Check. STEP 7 will provide you with possible solutions to any errors which
may have occurred.
