I am trying to replace PCU20 with PCU 50 6FC5120-0DF02-0AA0  windows NT  for 840D Powerline, 573.4

The used PCU50 is on German Language, Trying to switch the language , there is an error   no  language toolkit.

Any help , to activate the English language?  

update: two system message  are shown at the start:

Thank you for the reply.  How about importing the file from similar pcu? 

 thank you  for your help.

I already put back the PCU20, and it is in English  working fine no  alarms. We actually replacing it with PCU 50  for Drive parameterization and Magazine commissioning.  However, the  used PCU 50 apparently  was used for WIESS  machine  and has English language problem.  So we are reluctant to buy  another used  PCU.  we will give it try  to fix  the mmc.  I have seen mmc arc file  in the files  list, may be there is backup.

 By the way  , can I work  on the PCU 50  using normal monitor +keyboard and mouse?

 Yes that is another way, but how can you get another PCU 50? and how do you know where from and where to and what files or folders to transfer ? 

I really use you mentioned way fixing one PCU 50 , but which was only missing one file from Windows System. 

So like I suggested option#2 --it would be easier to do than transfer

I really want to help you.  can you connect PCU20 back and post the picture of you screens , and what kind of machine(mill, turning, ) you have who is machine builder? --I can give you suggestion--maybe you cannot upgrade  to PCU 50
