Checks on run times
It is possible to configure checks on observance of the run times in the system.The possible checks are:check on the maximum run duration (complete running); error at first occurrence of the event (GPV_ALARMTIME_xxx)check on the maximum run duration (incomplete running, endless loop check); error at first occurrence of the event (GPV_PERIOD_xxx)check on the maximum repeated run duration (complete running); error at first occurrence of the event due to a configurable number of consecutive cycles (GPV_WARNINGTIME_xxx)The checks can all be configured for every single PLC task.The configuration of the checks takes place at run time through system variables.Note: as reference for the checks described is made to the task run times, remember that these are shown in the time diagrams with “t”, while the relative values are contained in the variables “GPV_CYCDURxxx”.GPV_ALARMTIME_xxx and GPV_WARNINGTIME_xxx parameters are best suited for accurate control; default value for both is 0 (disabled).Parameter GPV_PERIOD_xxx is optimal to check never ending loop task condition and should be typically configured with values multiple of the requested task period; default value is 10 * requested task period.FAST TaskControl configuration variables (all wr)
