Why I can not open FB in S7-Graph?

I uploaded complet program to my Notebook,but I can not open one FB /I have DB for this block too/!!!It cannot be opened online too. I do not know why...When trying to open it,there is a message-The block cannot be opened because the description of the local variable does not exist.Either use the original block or try opening with the SKA.Machine works without problems....Is here anyone who can help...Thanks.

Maybe it is a Know-how-protected??

it is not protected...

...because the description of the local variable does not exist.

The original programmer has been a bit careless. He changed the FB (or the DB) offline and forgot to update both online. Try to open it in STL (AWL).

Thanks You a lot,I opened it in STL...And now,can I anyhow regenerete this FB back in Graph??? Thanks

Not sure if you look for this but to be sure make a copy of your program.
Do next edit -> check block consistency -> compile/compile all

can't open it because it is in tsjechisch sorry

You could open it now...I hope...I set neutral language...Good night

DB20 in this project has no data in it. As DB20 is the instance DB for the call to FB20 the plc goes into stop.

Where did the DB20 in this project come from ?

there are several errors when i try to compile it

1. Description of Error:
The called block is not available, it must be compiled before being called.
To Correct or Avoid Error:
In the case of system function block (SFB)/system function (SFC) calls, copy to your offline database using the SIMATIC Manager. If the called SFB/SFC is not available on the addressed CPU, it must not be called.

2. Description of Error:
Only one instance DB can be automatically generated for each S7-GRAPH FB. During an automated process for generating a DB, the system found an S7-GRAPH FB that contains two instance DBs in the project.
To Correct or Avoid Error:
Open the S7-GRAPH FB and generate the two instance DBs manually and in sequence.

3. Description of Error:
This is just a warning. No type description is available for the block you called.
To Correct or Avoid Error:
Check the language settings in the Program Editor which also determine the offline database.

4. Description of Error:
Syntax errors are present in the compiled file or in the user entry. If a "Details" button is displayed, click it to find out more about the cause of error.
To Correct or Avoid Error:
Check your entries.
