Commissioning the S7–400H
Follow the steps outlined below to commission the S7–400H:
1. In SIMATIC Manager, open the sample project "HProject". The configuration corresponds
to the hardware configuration described in "Requirements".
2. Open the hardware configuration of the project by selecting the "Hardware" object, then
by right-clicking and selecting the shortcut menu command "Object -> Open". If your
configuration matches, continue with step 6.
3. If your hardware configuration does not match the project, e.g. there are different module
types, MPI addresses or DP addresses, edit and save the project accordingly. For
additional information, refer to the basic help of SIMATIC Manager.
4. Open the user program in the "S7 program" folder.
In the offline view, this "S7 program" folder is only assigned to CPU0. The user program
is executable with the described hardware configuration. It activates the LEDs on the
digital output module (running light).
5. Edit the user program as necessary to adapt it to your hardware configuration, and then
save it.
6. Select "PLC -> Download" to download the user program to CPU0.
7. Start up the S7-400H automation system by setting the mode switch of CPU0 to RUN
and then the switch on CPU1. The CPU performs a restart and calls OB 100.
Result: CPU0 starts up as the master CPU and CPU1 as the reserve CPU. After the
reserve CPU is linked and updated, the S7-400H assumes redundant mode and
executes the user program. It activates the LEDs on the digital output module (running
light).
Note
You can also start and stop the S7-400H automation system using STEP 7.
For additional information, refer to the online help.
You can only initiate a cold restart using the programming device command "Cold
restart". For this purpose, the CPU must be in STOP mode and the mode switch must be
set to RUN. OB 102 is called in the cold restart routine.
