Your search a variable/function which gives you the cycletime of the Backgroundtask? If yes then there are two ways: 1.) use systemfunction _getCurrentTaskIDRunTime /getAverageTaskIDRunTime 2.) use systemvariables: taskruntime.background /effectivetaskruntime.background (set systemvariable taskruntimemonitoring to enablebefore!)

Iwould like calculate the cycle time of a movement (e.g. a stroke of a cylinder)adding the time of Background task at the previous cycle while the command is active. Best Regards Davide

This is my part of program TimeBackground :=_getcurrenttaskidruntime(_task.backgroundtask); were TimeBackgroundis time type. I tried to use also TimeBackground :=_getcurrenttaskidruntime(); but it doesn't change anything. Someone can help me? Tankyou
