Dear ni lar ,

If it is an "instance data block" related to a function
block, please try to add cells in the FB parameters and
update corresponding DB.

Please upload snapshots for more information.

// Newly added information
What is the difference between an instance data block and a global data block and how does a CALL call influence the DB register?

Global data blocks	Instance data blocks
All blocks (FBs, FCs and OBs) can access the global DB in the program.	The instance DB is assigned to an FB.
You can create a global DB independently of other blocks in the program.	The instance DB can only be created when the associated FB is available in the program.
You cannot declare static local.	Static local data can be declared in the FB. The stored static local data is not lost when the block has finished and is retained over several cycles until it it is written again.
Adding, deleting and changing of variables is done in the data block.	Adding, deleting and changing of variables is done in the associated function block.
Initial and current values can be changed in the global DB.	Initial and current values cannot be changed in the instance DB.
The structure in the global DB itself can be specified.	The structure in the instance DB is predefined by the variable declaration in the associated FB.

Table 1

Best regards,
Hamid Hosseini
