Free function blocks (FFB) are enabled in two steps.
1. Parameter P2800 enables all free function blocks , normally (P2800 = 1)
2. Parameters P2801 and P2802 respectively, enable each free function block individually (P2801[x] > 0
oder P2802[x] > 0)
In addition, Parameters P2801 and P2802 determine the chronological order of each function block. The
following table shows that the priority increases from left to right and from bottom to top.

FFBs will be calculated in following order:
P2802[3], P2801[3] , P2801[4], P2802[4]
Dependency:
- Set P2800 to 1 to enable function blocks.
- All active function blocks will be calculated in every 132 ms.
