When the limit is exceeded, an error message is iisued 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 of 10 ms, as then, the blocks will not then start with the starting pulse.
Maximum Number of TICKS on the Task Levels
MW_BEARB (measured value processing)
PLC1_BEARB (slow PLC processing)
PLC_BEARB (fast PLC processing)
SFS_BEARB (switchgear interlocking)
1)
When the sum of TICKS of all blocks exceeds the above-mentioned limits, an error message is output in the
CFC.
