Structural planning and implementation of a microprocessor-based human-machine interface in a steam-explosion process application
In this paper, small-scale microprocessor-based human-machine interface (HMI) and programmable logic controller (PLC) standard software libraries are applied to plan, design, implement, and construct models for creating the modular application software. The graphical user interface (GUI) functions used in a specific biomass steam-explosion process, intended to be integrated with the PLC device for HMI, thereby providing excellent GUI-based supervision and control functions. Reviewing these specific case study results, we find that the major advantage is maximum system operating performance at minimum cost. Also, the GUI/HMI operation effectively provides user-friendly and reliable interactions. This GUI/HMI approach is a very cost-effective technique. (C) 2010 Elsevier B.V. All rights reserved.
