On Saving
• Include instance DB:
If you select this option, whenever a function block is compiled or downloaded,
S7-Graph checks whether the instance DB requires updating and if necessary
updates it automatically.
If you do not select this option, you must create or update the instance DB
manually with the menu command File > Generate Instance DB.
Caution:
If you have set the option "Message with ALARM_SQ/ALARM_S
(SFC17/SFC18)" in the "Messages" tab page (Options > Application Settings
menu command) the instance DB is automatically included. If the instance DB is
deleted, make sure you only recreate it with S7-Graph, otherwise messages are
lost.

If you select this option, the reference data are created automatically when you
save the block.
If you do not select the option, you can nevertheless create or update the
reference data manually with the menu command Options > Reference Data.
