2.8.1
Runtime measurement
When the application has been started, the controller continuously carries out a runtime measure-
ment for the interval-controlled ApplicationTask, the interval-controlled UserTask and the idling Id-
leTask.
• The runtime is the time from the starting time of the task to the time where the processing of
the task logic has been completed, including all interruptions (e.g. by higher-priority tasks).
• The runtime measurement also includes an operating system part of the Servo Drive 9400, the
runtime of which depends among other things on the plugged-in modules.
• The current and maximum task runtimes are displayed in the following display parameters:
• The device command C00002 = "36: Reset runtime measurement" serves to reset the runtime
measurement, e.g. the memory for the maximum values is reset to "0".
