S5-95F
15.7
Evaluating Cycle Time Statistics
The S5-95F collects statistical data on cycle times. This statistical data is located in internal RAM in
the address space extending from 8004
invoking the programmer function OUTPUT ADDRESS.
Functionality
The S5-95F computes the time needed for each cycle and assigns it to an interval. A counter is
then assigned to each interval. The S5-95F increments a counter by one whenever the cycle time
being measured belongs to that counter's interval.
The statistics function is located in internal RAM and comprises
•
95 counters of 2 bytes each (see Table 15-4) and
•
a control byte
