Note
After changing the hardware configurat
ion, download takes place practically automatically.
This means that you no longer need to perform the steps described in sections
Step 2:
Stopping the reserve CPU
(Page 162) to Step 5: Transition to redundant system mode
(Page
164). The system behavior remains as described.
You will find mo
re information in the HW Config online help "Download to module ->
Download station configuration in RUN mode".
10.6.2
Step 1: Editing parameters offline
Starting situation
The fault-tolerant system is operating in redundant system mode.
Procedure
1. Edit the module parameters offline in HW Config.
2. Compile the new hardware configuration, but do
not
load it into the target system just yet.
Result
The modified hardware configuration is in the PG/ES. The target system continues operation
with the old configuration in redundant system mode.
10.6.3
Step 2: Stopping the reserve CPU
Starting situation
The fault-tolerant system is operating in redundant system mode.
Procedure
1. For CPU access protection with password: In SIMATIC Manager, select a CPU of the
fault-tolerant system, then select
"PLC > Access Rights > Setup" from the menu. Enter the CPU access password.
2. In SIMATIC Manager, select a CPU of the fault-tolerant system, then select "PLC >
Operating Mode" from the menu.
3. In the "Operating Mode" dialog box, select the standby CPU and click "Stop".
