Coordinators
The coordinator function is for devices that are used to coordinate the flow information regarding the Helium Recovery System through the network so that it reaches the database.
In practice, it specifically refers to the coordinators, also called base stations, manufactured by HZB. They use the XBEE protocol to communicate and read information from the various vessels, cryostats, etc. in a facility and send that information to the server so it can be saved in the database.

Because the coordinator function was made just for the base stations, this function only has one object class. This class is called Coordinator and is the class for all of the base stations.
The coordinator object class has a position type of 1.
| Status | Meaning |
|---|---|
| 0 | inactive |
| 1 | open |
| 2 | not connected |
No measurements types are defined for the Coordinator class.
For the same reason the coordinator function has only one class, the Coordinator object class only has one object type, called Coordinator default.
