OOI CI LCA REVIEW August 2010 Status of Progress Scenario for "Command An Instrument" UC.R1.18 User determines command(s) that are to be applied to an instrument. User accesses that instrument's general instrument interface supplied by CI, and learns whether he/she has access to the necessary commands. If the user needs additional permissions that are part of the general interface, these are requested. Commands available through the general interface may be accessed directly through the interface. These commands are directed to the Instrument Agent, which uses its knowledge of the instrument to assess their validity under current operating conditions. If the user needs direct access to the instrument, the user requests that (see Direct Instrument Interface). The Instrument Agent conveys the command to the instrument, logging and displaying the response and any resulting state changes. 20
