3.39 Free function blocks (FFB)
P2800 Enable FFBs Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: TECH Active: first confirm QuickComm.: No Max: 1
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).
Possible Settings:
0 Disabled
1 Enabled
Dependency:
All active function blocks will be calculated in every 132 ms.
P2801[17] Activate FFBs Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: TECH Active: first confirm QuickComm.: No Max: 3
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.
