Technical Data
4.19 User-defined Functions (CFC)
General Limits
Maximum number of all CFC charts
considering all task levels
Maximum number of all CFC charts
considering one task level
Maximum number of all CFC inputs
considering all charts
Maximum number of reset-resistant
flipflops
D_FF_MEMO
Device-specific Limits
Maximum number of synchronous
changes of chart inputs per task level
Maximum number of chart outputs per
task level
Additional Limits
Run-Time Level
MW_BEARB
PLC1_BEARB
PLC_BEARB
SFS_BEARB
1)
When the limit is exceeded, an error message is output by the device. Consequently, the device starts mon-
itoring. The red ERROR-LED lights up.
2)
The following condition applies for the maximum number of timers: (2 · number of TIMER + number of
TIMER_SHORT) < 30. TIMER and TIMER_SHORT hence share the available timer resources within the
frame of this inequation. The limit does not apply to the LONG_TIMER.
3)
The time values for the blocks TIMER and TIMER_SHORT must not be selected shorter than the time res-
olution of the device, as the blocks will not then start with the starting pulse.
Maximum Number of TICKS in the Task Levels
MW_BEARB (Measured Value Processing)
PLC1_BEARB (Slow PLC processing)
PLC_BEARB (Fast PLC Processing)
SFS_BEARB (Interlocking)
1)
When the sum of TICKS of all blocks exceeds the limits before-mentioned, an error message is output by
CFC.

Limit
32 When the limit is exceeded, the device rejects the parameter
set displaying an error message, restores the last valid pa-
rameter set and uses it for restarting.
16 When the limit is exceeded, an error message is output by
the device. Consequently, the device is put into monitoring
mode. The red ERROR-LED lights up.
400 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
350 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
Limit
165 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
