Meter data request/query sequence
The controller requests meter data by specifying the meter data address and the minimum transmission interval.
The meter transmission stops after 10 seconds. To continue receiving data, make another request before the 10 seconds pass.

Snapshot (preset) recall request sequence
Upon receiving a result notication in response to a snapshot (preset) request, you need to execute the parameter sync sequence.

sync sequence
In addition, if a snapshot (preset) recall occurs internally in the controlled device (e.g. by front panel button press) or when such a request is
received from another controller, the controller receives a change notication that indicates that all parameters have changed (see the next
section). If this occurs, the controller needs to execute the parameter sync sequence.
