Comparing offline and online CPUs

You can compare the code blocks in an online CPU with the code blocks in your project. If

the code blocks of your project do not match the code blocks of the online CPU, the

"Compare" editor allows you to synchronize your project with the online CPU by downloading

the code blocks of your project to the CPU, or by deleting blocks from the project that do not

exist in the online CPU.

Select the CPU in your project.

Use the "Compare Offline/online" command to open the

"Compare" editor. (Access the command either from the "Tools"

menu or by right-clicking the CPU in your project.)

Click in the "Action" column for an object to

select whether to delete the object, take no

action, or download the object to the device.

Click the "Synchronize" button to load the code

Right-click an object in the "Compare to" column and

select "Start detailed comparison" button to show the

code blocks side-by-side.

The detailed comparison highlights the differences

between the code blocks of online CPU and the code

blocks of the CPU in your project.
