It is mandatory to correctly set (at runtime) the Executable and UserExecutable attributes to indicate if a Method may be called in the current state of the Analyser Server and if the currently logged-in user may request its execution.
Vendors have the right to add custom methods to each component of the system. For example:
LoadFirmware Method at the AnalyserDevice level. MoveToNextSample Method on a multi-sample holder accessory. All Methods shall be located on the MethodSet Object when the component is a TopologyElement.
