4.
There is an elegant method to save time, if you want to define several tags in a
network. Assign all tag names first of all. Then define all tags at the same time with
the dialog of step 4.
Note You will find further information in the following entry:
Why is universal definition and utilization of symbols in STEP 7 (TIA Portal) V12
obligatory for the S7-1500?

ARRAY data type and indirect field accesses

The ARRAY data type represents a data structure that consists of several elements
of the same data type. The ARRAY data type is suitable, for example, for the
storage of recipes, material tracking in a queue, cyclic process acquisition,
protocols, etc.

You can indirectly access individual elements in the ARRAY with a runtime tag
(array ["index"]).
