No further actions may be performed on the system during the upgrading process!
Prior to upgrading the operating systems, the HIMax system must be in a faultless state!
NOTE
Service interruption possible during the loading procedure!
Ensure the operation of a functional, redundant module! The redundant module
maintains operation during the loading procedure.
To load a new operating system into all modules
1. Extract the zip file delivered by HIMA in a folder.
2. Connect the PADT with the processor module via Ethernet.
3. Start Online mode in the SILworX Hardware Editor.
Log in to the system using the IP address of the processor module.
4. Stop the processor module's system operation prior to loading to a processor module.
If a second processor module exists, it adopts system operation. Otherwise, log in to the
module once again.
5. Load the operating system using the context menu. Use the file specified in
Table 25
from the folder created in step 1.
- Restart the module. If a fault occurred while loading the operating system, the OS
loader is started. If the OS loader was not upgraded at this point, it is only accessible
via the standard IP address.
The normal operating system now uses the previously configured IP address.
- Restarting after loading the operating system of the module connected to the PADT
causes the connection to be closed. Log in again.
- Upgrade the OS loader. The OS loader once again operates with the configured IP
address.
6. Only load the second processor module, if the first one is in RUN.
7. Perform steps 4 through 6 for all other processor modules.
8. Update the system bus module: First update the system bus module located in slot 1 of
each base plate, then the system bus module in slot 2 of each base plate.
To be able to update, first stop the system bus module, then proceed as described in
step 5.
9. Update all communication modules. To do so, first stop the communication module, then
proceed as described in step 5.
10. Update all I/O modules. To do so, first stop the I/O modules, then proceed as described
in step 5.
All modules operate with the new operating system.
5.6.2 Updating and Downgrading Operating Systems
In seldom cases, it can make sense to load a previous operating system version into the
module:
If a controller has run for a long time without modification and an individual module must be
replaced, it may be better to import the existing operating system version into the new
module. The existing operating system version may be better suited for use with that of the
remaining modules.
