Do not switch the controller off!
The controller can be damaged by interrupting the downgrade process.
Do not switch the controller off during the downgrade process and do not
disconnect the power supply!
Note the firmware version
For devices with a factory installation of a firmware >= FW 05, a simple
downgrade to a version <= FW 04 is not possible!
Use a special downgrade image.
Proceed as follows if you want to downgrade the controller to an earlier firmware
version:
1.
Save your application and the controller settings.
2.
Switch off the controller.
3.
Insert the memory card with the new firmware image into the memory card
slot. Use a special downgrade image if necessary.
4.
Switch on the controller.
5.
After booting the controller, launch the WBM "Create Boot Image" page
(you may have to temporarily change the IP address).
6.
Create a new boot image on the internal memory.
7.
Switch off the controller after completing the process.
8.
Remove the memory card.
9.
Switch on the controller.
The controller can now be started with the new firmware version.
