Function description
14.2 Function description
With an online connection to the controller, use the oscilloscope user interface of the
»Engineer« to set the trigger condition and the sample rate and select the variables to be
recorded.
When the measurement is started, the set parameters are transferred to the controller and
checked. If invalid settings are found, the oscilloscope sends an error. Otherwise, the
measurement is started.
With an online connection, the measured controller data are transferred to the »Engineer«
and graphically represented on the oscilloscope user interface as soon as the measurement
has been completed.
Recording variable values
The operating system scans the oscilloscope in fixed 1 ms-cycles, i.e. the oscilloscope can
record variable values with a sample rate of max. 1 kHz.
Recording system variable values of the internal motor control
Unlike the variables declared in the application, the system variables of the internal motor
control (MCTRL) can also be recorded with a sample rate higher than 1 kHz.
Recording I/O variable values referring to a task
When selecting the variables to be measured, it is possible to indicate a task reference for
the variables. If the behaviour of a certain task is to be examined, you can indicate the task
reference to exactly record the values valid for the task run-time.
r The variable values are recorded during the process output image generation of the
task.
Note!
In the servo operating modes, recordings with a time-based resolution of 31.25
μs and 125 μs are not possible!
