The figure below shows the view in STEP 7, the logical view and the physical view of the
configuration with two integrated IO devices in system redundancy. Note that the view in
STEP 7 does not exactly match the physical view.

Commissioning a system-redundant configuration
It is imperative that you assign unique names during commissioning.
Proceed as follows when you change or reload a project:
1.
Set the fault-tolerant system to STOP on both sides.
2.
Reset the standby CPU memory.
3.
Download the new project to the master CPU.
4.
Start the fault-tolerant system.
Note
Use the topology editor in HW Config.
