Hi, M.M1365,

1st of all making sure you are the Not same person M._GH, Who post topic 

But 2nd I just guess both of you have the similar issue. the OEM display , and I read your screen text in German. --in English : like "Actual Value" , "Travel to Reference point " 

some thing like your machine going into some operation Mode  .

I know Siemens 880 , but I am sure your display is not standard Siemens one.

according to your description , can you check do you have something defective when you withdrawing some  HW when power is on.

Tips. If you know the OEM/machine builder 's name, search online to see there is still some one using similar machine or OEM forum , which people can help 

It's very hard for people here to help remote , also 880 is very old control no Siemens support any more

Hi

I have some problem sinumerik 880t , I wanted to connect to the plc on the cpu, but by mistake, while the machine was on, I pulled out the third card on the RAM module and the machine failed.

But I turned the car off and on, the alarm went off and the axles moved.

But the monitor image is not complete and does not change anything.

Help me please
