 Hello,

In the optimized access to blocks, it is not possible to have the offset value.For your case:

To set the block access, proceed as follows:

1. Open the "Program blocks" folder in the project tree.
2. Right-click on the block whose block access you want to change.
3. Select the "Properties" command in the shortcut menu.

   The properties dialog box of the block opens.

4. Click "Attributes" in the area navigation.
5. Enable or disable the "Optimized block access" option.
6. Confirm your entries with "OK".

I hope this helps,
