Step 6: Transition to redundant system state
Starting situation
The fault-tolerant system is operating with the new hardware configuration in single mode.
Procedure
1. In SIMATIC Manager, select a CPU of the fault-tolerant system, then select "PLC >
Operating Mode" from the menu.
2. From the "Operating Mode" dialog box, select the reserve CPU, then click "Warm
Restart".
Result
The reserve CPU links up and is updated. The fault-tolerant system is operating with the new
hardware configuration in redundant system mode.
Note
Any set up access right is not canceled until you stop the SIMATIC Manager. You should
reset the access right once again to prevent unauthorized access. You reset the access right
in the SIMATIC Manager with the menu command PLC > Access Rights > Cancel.
