Parameter Function
P2801[0...16] Activate FFBs
P2801 and P2802 respectively, enable each free function block individually (P2801[x] > 0 or P2802[x] >
0). In addition, P2801 and P2802 determine the chronological order of each function block by setting the
level in which the free function block will work.
The following table shows that the priority decreases from right to left and from top to bottom.

Example: P2801[3] = 2, P2801[4] = 2, P2802[3] = 3, P2802[4] = 2
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 128 ms, if set to level 1 to 3. Fast free function blocks
(level 4 to 6) will be calculated in every 8 ms.
