changes of chart inputs per task level
Maximum number of chart outputs per
task level

SFS_BEARB
1) When the limit is exceeded, an error message is iisued by the device. Consequently, the device starts moni-
toring. 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 resolu-
tion of the device of 10 ms, as then, the blocks will not then start with the starting pulse.
Maximum Number of TICKS in the Task Levels
Task Level
MW_BEARB ((Measured Value Processing)
PLC1_BEARB (Slow PLC Processing)
PLC_BEARB (Fast PLC Processing)
SFS_BEARB (Interlocking)
When the sum of TICKS of all blocks exceeds the limits before-mentioned, an error message is output by
