attpcdaq.daq.models.ECCServer.change_state¶

ECCServer.change_state(target_state)[source]¶

Tells the ECC server to transition the data source to a new state.

If the request is successful, the is_transitioning field will be set to True, but the state field will not be updated automatically. To update this, refresh_state() should be called to see if the transition has completed.

Parameters:	target_state (int) – The desired final state. The required transition will be computed using `_get_transition()`.
Raises:	`RuntimeError` – If the data source does not have a config set.
