A method of determining tuning parameters for a plurality of field devices (44), comprising the steps of:? Determining process features by at least one of the plurality of field devices (44); Figs; Transmitting the process characteristics to a tuning system; Figs; Generating, by the tuning system, a robustness map (106) having a plurality of robustness qualities according to the process control features, the robustness map (106) comprising a plurality of points each associated with a set of a plurality of sets of tuning parameters; Figs; Selecting a robustness quality by selecting a point in the robustness map (106); Figs; Calculating another set of tuning parameters according to the selection; Figs; Controlling the plurality of field devices (44) in accordance with the set of tuning parameters by a controller (12); wherein the step of generating the robustness map (106) includes the step of graphically representing two or more robustness qualities, the method comprising the steps of: Creating a tuning parameter range for at least one of the tuning parameters; Figs; Varying one of the robustness qualities over a robustness quality range; Figs; Varying the one of the tuning parameters over the tuning parameter range at each of a first number of selected points within the robustness quality range; Figs; Determining a second tuning parameter and another of the robustness qualities for each of a second number of points within the tuning parameter range for each of the first number of selected points within the robustness quality range.
