Location of the 
firmware file
In the "Firmware File" group, specify the folder where you placed the file for 
the firmware update. If you want to search, you can use "Browse" to open 
Explorer.
Activation of "new" 
firmware
Use the "Activate firmware after download" check box to specify when the 
"new" firmware is to be activated as follows:
● Select the "Update firmware after download" check box if the IM is to 
perform an automatic RESET after the new firmware was successfully 
loaded. The new firmware is active following the restart.
● Clear the "Update firmware after download" check box to prevent the IM 
from performing a RESET reset the new firmware was loaded. The "new" 
firmware becomes active only after the power supply has been switched 
off.
Firmware update in a redundant system
After the firmware update of the active IM, the "RESET" automatically triggers the switchover 
of the two IMs. 
You can now update the second IM in the redundant system. Each IM must be updated 
separately. 
Updating the identifier
 
 
Note
After the firmware update of the IM has been successfully completed, update the identifier of 
the firmware version. You can find information on this in the section "Hardware Updates 
(Page 32)".
