Etere allows configuring two Automation controllers to run simultaneously on different servers (a main and a backup) to improve fault-resilience, by allowing an automation controller to replace the other controller in case of an unexpected failure (i.e. interrupted communication).
In order to implement a main/backup function for the EA1790 Control Panel, follow the procedure below:
1.Start the Main automation controller Launch an Automation controller on a certain server, if it is the first automation controller running in the LAN it will start functioning in main mode (i.e. listening and executing all commands received from the EA1790 Control Panel).
2.Start the Backup automation controller Launch an Automation controller on another server, if it finds there is another automation controller already running in the LAN it would start function in backup mode (i.e. only listening the commands received from the EA1790 Control Panel).
3.Switch from Main to Backup
In a main-backup implementation, the backup automation controller would becomes main if the main automation controller is closed or it stops sending communication heartbeats to the backup automation controller (e.g. the server is down, the server is disconnected from the network, etc).
