Time isin microseconds.The timeout value for the task.Time is in microseconds.Value of WALLCLOCKTIME when the last execution of the taskwas started. DINT[0] contains the lower 32 bits of the value;DINT[1] contains the upper 32 bits of the value.Provides status information about the task. Once the controller setsone of these bits, you must manually clear the bit.To determine if:Examine this bit:An EVNT instruction triggered 0the task (event task only).A timeout triggered the task 1(event task only).An overlap occurred for this 2task.Time limit for execution of all programs associated with this task.Time is in microseconds.If you enter 0, these values are assigned:Time:Task Type:0.5 sec periodic or event5.0 sec continuousPublication 1756-RM003I-EN-P - January 2007
