| fromSequenceNumber | The starting sequence number for the Requested Results. It is a required argument if results are requested based on the input sequence number range. It shall be a valid value > 0. If 0, then fromTime and toTime are used. |
| toSequenceNumber | The ending sequence number of the Requested Results. It is a required argument if results are requested based on the input sequence number range. It shall be a valid value > 0 and shall be >= fromSequenceNumber. If 0, then fromTime and toTime are used. |
| fromTime | It is the start time for the Requested Results. This argument is considered only when fromSequenceNumber and toSequenceNumber are set as 0. |
| toTime | It is the end time for the Requested Results. This argument is considered only when fromSequenceNumber and toSequenceNumber are set as 0. |
| requestedMinimumDurationBetweenResults | The client can use this argument to configure a time interval between each Result to optimize the number of Results sent from the Server. The Server can return the revised interval if the requested interval is not supported. Note: It is only a requested minimum time interval by the client and the server could take additional time for processing. |
| revisedMinimumDurationBetweenResults | It is the minimum revised interval supported by the server. |
| status | It provides the status of the Method execution. Refer 7.4 for details. |
| statusMessage | It provides the high-level status information in a user-friendly text. |
