Virtual device aggregation

The “Virtual device aggregation” source can be used to obtain data from virtual devices. This option is used to obtain several data points at the same time, for example to perform a summation. To do this, select the “Virtual devices” option [1] under Source. A selection field [2] then opens, in which a virtual device can be selected by entering the name or ID. The desired data points of the virtual device whose data is to be transferred are then selected.

Once the data has been selected, the “Aggregated value preview” item [3] contains an example of the input value that can be used for the calculation in the Transformer.
