FC:

In the 'overview' choose the map 'FC-blocks' and select the FC you with the left-mouse-button. Keep the left-mouse-button pressed and drag the FC into the network you want.


DB:

there are two options:

1) using DB-call, indirect access

this method is faster if you use many DB-instructions because you will only open the DB one time.

2) direct DB-access.
