6.2.21.4 Further task dependencies
• Parameter st35 system counter increases by the value 2 after 8 times the "basic
Tp" time.
• The times for the offline mode of04 time base must be written with a multiple of
the basic Tp.
• By increasing the Tp, more computing power is available for additional func-
tions.
• The cycle times of the controllers and I/O functions increase by the same factor
as the basic process time.
6.2.21.5 Runtime monitoring
The maximum running time of the three main interrupt sources is monitored. If too
many functions are activated and the limit value is exceeded, "error runtime" is trig-
gered.
Time measurement of the periodic call of the fast interrupt in µs
Current runtime of the fast interrupt in µs.
Mean value of the runtime of the fast interrupt in µs.
Drag pointer of aa86. The maximum runtime is determined in
the fast interrupt. Resettable with reset.
ERROR runtime is triggered, if the value in aa88 exceeds the
limit value of aa89 defined by KEB.
Time measurement of the periodic call of the mean interrupt in
µs.
Current runtime of the mean interrupt in µs.
Mean value of the runtime of the mean interrupt in µs.
ERROR runtime is triggered, if the value in aa93 exceeds the
limit value of aa94 defined by KEB.
Time measurement of the periodic call of the slow interrupt in
µs.
Current runtime of the slow interrupt in µs.
Mean value of the runtime of the slow interrupt in µs.
ERROR runtime is triggered, if the value in aa98 exceeds the
limit value of aa99 defined by KEB.
