1. Creating a project and R-CPUs
1. Create a new project in STEP 7. Give the project a name.
2. Select CPU 1515R-2 PN from the hardware catalog in the network view of the hardware
configuration.
3. Drag and drop the CPU to the task window in the network view.
Result: STEP 7 automatically creates both 1515R-2 PN CPUs for the redundant system.
STEP 7 displays both CPUs in the network view graphically.
Note
Deleting CPUs from the hardware configuration
You can only delete the two CPUs as a pair.

1. Open the CPUs in the device view. In the device view, the first CPU and the second CPU
are each in slot 1. Slots 0 to the left of the CPUs are reserved for system power supplies
(PS).
2. Give the CPUs unique names under Properties.
