Downsampling 1Ch

Downsampling 1Ch processes the values of the input channel with a configurable downsampling factor. This achieves downsampling so that the output signal is a representation of the input signal at a lower sampling rate. This can be useful, for example, to better identify trends or to perform subsequent compression of highly sampled signals if only lower sampling rates are required within the analysis. This is a simple way to increase the performance of the analysis.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Downsampling Factor: the factor used for downsampling. For example, if the downsampling factor is 100, only every 100th value is saved. The sample time is thus 100 times the original cycle time, which lies between two sampled data points. If the downsampling factor is set to one, all values are buffered.

Output values

• Output Value: output signal with the sampling rate lower by the downsampling factor.

Standard HMI Controls

For the Downsampling 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The SingleValue Control visualizes the output value Output Value.

Alternatively, customer-specific HMI controls can be mapped in the Downsampling 1Ch algorithm using the Mapping Wizard.
