2. Select the S7 or M7 program in the online window of the project or the node in the "Accessible
Nodes" window.
3. Select the "Blocks" folder on the CPU which you want to save using one of the following
methods:
- In the online window of the project if you are working with project management
- In the "Accessible Nodes" window if you are working without project management
