Visualize DB variables in pcs7 with winCC?

Hm. Is it a Instance DB or a Shared DB?

It's a shared. An instance DB get's it's values from the FB and you can't modify them. So, if you are to create an SCL source, then all values: VAR_INPUT/OUTPUT/IN_OUT/VAR are listed in the instance DB.

Okey, I got it working in a new DB with an BYTE (not an array). Do you know how I can set that variable = ARRAY[0] in my other DB? 

You cannot use Arrays with the S7_m_c. See my first post for the data types that are permitted.

 I think you have to create an SCL source for that. You will then use the following code, for example:

ByteOutput1 :=ARRAY[0];

ByteOutput2 :=ARRAY[1];

etc.

This way, you can declare bytes as VAR_OUTPUT which you address your array to.
