UNICOS Essentials

UNICOS establishes...

 

  • A well defined set of standard device types (objects), both in the control and supervision layers, modeling most of the equipment and needs of continuous processes.
  • The relationships between them
  • A formalized way of :
    • Define the control units of a process  (best practises inspired in the ISA-88 standard: Batch processes)
    • Programming the specific process logic for those units

UNICOS not only a bunch of devices...

 

  • DEVELOPMENT: Provides the developer with tools to produce rapid control applications. Automatic generation of code.
  • COMMISSIONING: Allows early plant commissioning, reducing check tasks to the instruments and electrical level (cabling). Access to devices without SCADA development.
  • OPERATION:
    • Provides the operator a standard way to interact all the objects
    • Navigation capabilities between panels and trends: WWW browser-like, contextual buttons, pop-up navigation
    • Process Alarms and Event list
    • Access Control
  • DIAGNOSTICS: Tools to diagnose problems (process alarms, Infrastructure: control components,¿)
  • MAINTENANCE: Allows optimized code evolution and maintenance by a reduced development team

UNICOS methodology

 

  • Specifications creation
    • Instances: data captured by filling EXCEL (XML) worksheets. (Eventually these specifications may be created also automatically (e.g. DB oriented))
    • Functional Analysis + Logic specification: Word templates
  • Automatic generation (UAB: UNICOS Application Builder)
    • Instance generation
    • Standard Logic generation
  • Manual intervention
    • Process logic coded by the control engineer in an standardized way. Some applications may create automatically the logic based on templates.
    • Process synoptics: drag & drop
  • Support
    • Documentation
    • Tutorials
