A more complex node acting as server and client.
|
|
This node claims a position number and registers its message and items interface.
|
|
The Distributor is based on the class NodeStates and supports the following messages:
|
|
- topic = "on", payload = nil
|
|
- topic = "off" , payload = nil
|
|
- topic = "state", payload = nil,
|
|
response is "running", "stopped", "standby", "defect", or "not supported"
