Schedule Model combined with Setting Group Control Model

Schedules (LN FSCH) and Schedule Controller (LN FSCC) operate on a single Data Object (controllable entity) only. In case you want to set several or even many values with the Schedule Model - you will fail to do so.
Is there a work-around? Yes!
You can control Setting Group Control Blocks through Schedules as shown in the following picture:

The example shows a schedule with 24 enumerated values (1, 2, 3). These values control the Setting Group Control. That way allows to schedule many values (in the example 9 values) with a single schedule! The Schedule Controller LN FSCC is not shown.
This example shows the flexibility of IEC 61850!
More to come!
