184CHAPTER 2 DEPENDENCE FUNCTIONS2.3.7 Measuring PerformanceIt is possible to measure the time and pass count between two events. Repetitivemeasurement can be performed while executing a program in real-time, and when done,the data can be totaled and displayed.Using this function enables the performance of a program to be measured. To measureperformance, set the event mode to the performance mode using the SET MODEcommand.■ Performance Measurement FunctionThe performance measurement allows the time between two event occurrences to be measured and thenumber of event occurrences to be counted. Up to 65535 event occurrences can be measured.● Measuring TimeMeasures time interval between two events.Events can be set at 8 points (1 to 8). However, in the performance measurement mode, the intervals, startingevent number and ending event number are combined as follows. Four intervals have the following fixedevent number combination:● Measuring CountThe specified events become performance measurement points automatically, and occurrences of that eventare counted.Interval Starting Event Number Ending Event Number1 1 22 3 43 5 64 7 8
