Add A Sensor Node

Sensor nodes in PolySync are directly associated with a hardware device or sensor. You will need to create a Dynamic Driver interface for each of the supported devices and sensors. These are typically provided with PolySync, but custom Dynamic Driver interfaces may also be [created](/articles/?p=563). Refer to the [Supported Sensors](/sensors/) section for specific instructions to configure each sensor. ### 1. Add a sensor node To add a new sensor node press the **Add Sensor Node** button in the bottom-left of the SDF Configurator. Select the sensor from the drop-down list and give the node a name. ![Add a Sensor Node](/wp-content/uploads/2016/10/sdfc-add-sensor-node.png) If the sensor is not listed in the drop-down menu, read here about [creating a Dynamic Driver Interface Workflow](/articles/?p=563). The SDF Configurator opens all Dynamic Driver interface files from the `polysync/lib` directory, for example `polysync/lib/`. ### 2. Configure the node parameters Once the node has been created in the SDF, the supported parameters for the node are automatically populated by the SDF Configurator with default values. Refer to the [Supported Sensors](/sensors/) section for specific instructions on configuring each sensor before [starting the node](/articles/?p=143). It's common that the IO and/or Sensor Parameters must be manually set before the node can be started successfully.
