Hello Guys,

I want to make a firmware update for my CPU 414-3 v3.02 to v3.1

I already downloaded the file. Is it possible to do it without a MMC. because the one I have is 1MB. They require at least 2MB for FW v<4.0 

Same question for CP 443-1 form v1.1.0 to v2.6

Regards,

Hello,

Practically in the firmware update manual is written the ways and Prerequisites for firmware update. In case it said at least needs 2 MB there needs the same.

What are the MLFB numbers of CPU and CP?

Hello, 

These are the order numbers:

6es7 414-3xj00-0ab0

6GK7-443-1EX10-0XE0 

Is there any other way to update the firmware? Bypassing tne MMC method?

Thanks

Aaa, do you meant using CP to make 'online' update? 

No, it is not possible in your case.

Thanks,

I need to update them both...

I mean using another way. Other than using the MMC.

CP is OK - https://support.industry.siemens.com/cs/ww/en/view/12213669

CPU (your type) - it needs MMC.
