Vibrating wire dataloggers, such as Strands, Geokon Geonets or Dataloggers, or API-connected VW nodes, must be configured on the iTwin IoT application in order to begin collecting data and for certain calculated metrics to be accessible on the iTwin IoT platform. This article will review how to configure logger channels and provide an overview of the information inputs required to configure the VW sensor for calculated data metrics.
Please consult the article within this Wiki regarding your specific logger or API connection for instructions about adding that device. After the logging device has been added, follow the steps outlined below. In the example below, a Loadsensing Datalogger is being configured. The same workflow applies to all device channel configuration. Contact the Customer Success team if you have any questions regarding your specific device.
1. Navigate to the Connectivity Module.
2. Click on the Datalogger Device.
3. Navigate to the "Edit Configuration" page of the device by clicking on the name in the column on the left of the page.
4. Click the blue "Edit Configuration" button below the Channel Information portion of the page. The pop-up window illustrated below will open, allowing the configuration of logger channels. The number of channels available for programming will be read from the device and automatically populated within this window, typically varying between 1-32 channels depending on the device. The example below illustrates a two-channel logger.
5. By default, channels are turned off, thus not reading the device channel or populating a sensor this channel. The input configuration allows the user to turn the channel on by selecting "Vibrating Wire". Once "Vibrating Wire" is selected, the "Category" option becomes available for configuration.
6. The "Category" dropdown allows the user to select the sensor type installed on that channel (ie piezometer, strain gauge, pressure cell). Once a Category is selected, the "Sensor" dropdown will become available.
7. The "Sensor" dropdown allows the user to select the specific sensor manufacturer and/or model. This selection may dictate the calibration factor inputs explained in the following section. The feature is designed to match the manufacturer's calibration sheet information with the application's sensor input configuration.
8. Once all configurations have been made, click "Apply" in the pop-out window. The pop-out window will close, bringing the user back to the "Edit Configuration" page.
