Add A Binary Node
A PolySync runtime consists of one or more hosts with at least one PolySync node. Nodes are defined within the SDF Configurator, which creates a configuration for each runtime node and saves it to the PolySync System Design File (SDF). Nodes are then spawned using the PolySync Manager, or by referencing the node ID from the SDF Configurator. To add a binary node to the PolySync SDF, open the SDF Configurator. ```bash $ polysync-sdf-configurator ``` Select the host tab, and select "Add Binary Node" in the bottom left corner of the SDF Configurator. ![Binary Node](https://help.polysync.io/releases/2.0.7//wp-content/uploads/2016/08/binary1.png) Select the path to the executable file, and add any command line arguments that are needed. ![Binary Node](https://help.polysync.io/releases/2.0.7//wp-content/uploads/2016/08/binary2.png) The binary node is added to the list of defined nodes for this host on the left sidebar. All changes made in the SDF Configurator are saved automatically. ![Binary Node](https://help.polysync.io/releases/2.0.7//wp-content/uploads/2016/08/binary3.png) Once the node is defined, run either of the two commands below. **All enabled nodes** will be started by the PolySync Manager. ### Live context ```bash $ polysync-manager -n ``` ### Replay context ```bash $ polysync-manager -w -n ``` ### Manually starting nodes Nodes can be manually started by referencing the SDF Configurator Node ID.
