5.2.14 Reset runtime measurement
When the application is started, the controller continuously carries out a runtime measurement for
the interval-controlled application task, the interval-controlled user task, and the free-running idle
task and displays the current and maximum task runtimes via parameters.
The
C00002 = "36: Reset runtime measurement" device command is used to reset the runtime
measurement, i.e. the memory for the maximum values is reset to "0".
Possible status displays for this device command
