Hi
I have the following problem with my Siemens control system 3. Until recently it ran without problems, it was one of the cards that suddenly shows a periphery fault and I could not approach all points in programs anymore. Then we have drawn out the Ram card and entered the machine data again.
If I now select the MDI function, where I can usually enter the programs, then the programs always crashes and it only shows me the message, MDI program:
L ????????!

Does anyone know what I need to do to make this work again?

greetings

Hello
How exactly can I understand the term "Enter"? Do you want to write a new program or edit an existing one ?
Do you get the message MDI program: L ????????!, right after you went to Open up?
Then it could be that the program no longer exists in the memory.
