Summary: an array variable have to be provided which is reachable via ADS. This can be a PLC variable of
a POU or a defined array variable by the system manager or alternatively the ADS server of the terminals/
boxes device is just activated. This is then detected by Scope2.

Commissioning

Determination of the desired sampling rate
The necessary/desired sampling rate results from the selected cycle time and the set oversampling factor.
Automatic setting of the terminal/box by the selection of the sampling rate alone is not possible.
Maximum values: 50-fold oversampling, 50 kSP/s, cycle time 10 ms

Fig. 168: Sampling times in relation to cycle times and oversampling
Configurations that demand sampling times not divisible by 500 ns are not supported.
Setting the sampling rate
1. Select the terminal/box in the TwinCAT tree
2. Select the "DC/Oversampling" tab
3. Select the operating mode (1/2-channel)
