Accessing the Instance DB

You can access the instance DB internally, in other words within the S7-Graph FB
(for example as an action linked to an event) or externally, in other words outside
the S7-Graph FB (for example linked to a different block).
Accessing the Data of the Instance DB
You can access the instance DB with STEP 7 tools. We strongly advise, however,
that you do not edit the DB.
