chart for each task level (number of
unequal information items of the left
border per task level)
Maximum number of reset-resistant
flipflops

1)
When the limit is exceeded, an error message is issued by the device. Consequently, the
device is put into monitoring mode. The red ERROR-LED lights up.
2)
TIMER and TIMER_SHORT share the available timer resources. The relation is TIMER = 2
· system timer and TIMER_SHORT = 1 · system timer. For the maximum used timer number
the following side conditions are valid: (2 · number of TIMERs + number of TIMER_SHORTs)
< 30. The LONG_TIMER is not subject to this condition.
3)
The time values for the blocks TIMER and TIMER_SHORT must not be smaller than the time
resolution of the device, i.e. 5 ms, otherwise the blocks will not start with the starting impulse
issued.

When the sum of TICKS of all blocks exceeds the limits before-mentioned, an error indication
is output by CFC.
Limit
400 Only fault annunciation (record in device
fault log); here the number of elements of
the left border per task level is counted.
Since the same information is indicated at
the border several times, only unequal infor-
mation is to be counted.
350 When the limit is exceeded, an error
message is output by the device. Conse-
quently, the device is put into monitoring
mode. The red ERROR-LED lights up.
Limit
50 When the limit is exceeded, an error
message is output by the device. Conse-
quently, the device is put into monitoring
150
mode. The red ERROR-LED lights up.
