As in all and any visual and interactive simulation of the behavior of the phenomenon, our eyes attempt with all effort persuade us that we are seeing the development and the unroll of the "real" phenomenon, the operation of the "actual" equipment, but we never must lose of sight that, by better that it is, one handle only the simulation, with all abstractions, approximations and inherent imperfections, beyond of possible errors (bugs) that can occur in the computer programs.
Therefore, the simulation, even though absolutely without bugs, serves only for purposes of apprenticeship and preliminary tests of the simulated behavior.
To effective practical implementation of any control program, this one must, after initial recommendable exams into simulators, be exhaustively studied, planned, implemented and tested into real equipment to which it is destined, in actual conditions of operation.
