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.
