16.4.5 Changing the processing order
If you insert a function block into the interconnection, an order index is automatically assigned to
this function block. By means of this order index it is defined in which order the individual function
blocks are calculated at runtime.
• The first function block inserted contains the order index "1", the next function block inserted
contains the order index "2", etc.
• The respective order index is displayed in the header of the function block in the rectangle after
the block name.
[16-10] Example: Function blocks with order index
 Note!
When a function block is shifted, its order index is maintained.
The processing order influences the result!
• In certain cases it may be sensible to change the processing order, but if you select an
unfavourable processing order, errors may arise!
