Recorder

The recorder captures a function's output and stores it as timeseries data in the internal InfluxDB. Use it to record a data stream, visualize it in your Apps, or analyze it later. It records during build time (in test mode) and during the App's runtime.

Settings

• Measurement name: Fill the data point name box with a unique name. You need this name to find and read the recorded data.

• Recording type: Right-click the recorder to select how long the data is stored: 1 hour (H, default), 1 day (D), 1 week (W), 1 month (M), 1 year (Y), or downsampled (DS) for long-term storage in downsampled form.

If the Industrial Blockchain extension is available in your account, an additional Blockchain (BC) recording type appears. It stores the data in the blockchain instead of InfluxDB.

Reading recorded data

Click the letter icon inside the recorder to generate a matching readout function directly on the canvas. Depending on the recording type, this is the read or readDownsampled function of the internal InfluxDB (or the blockchain read function), preconfigured with your measurement name.
