EventTunnel
An EventTunnel node synchronizes its dynamic fields with all other EventTunnels with the same label. Only dynamic fields with the same name and type are synchronized. A change to any field is automatically send to all other fields. It is guaranteed that even the initial value is transfered to all other nodes. This node can be used to implement something like a global state that is reachable from Proto instances.

enabled | SFBool | inputOutput | TRUE | Enables or disables the node. A node that is disabled does not react to incoming events and does not send events. | |
