Reverse engineering of process control systems in CFC presentation

PLSDOC® CFC - Editing and Reverse Engineering of CFCs

Reverse Engineering and Design of CFCs


PLSDOC® CFC provides reverse engineering of process control systems in CFC presentation. PLSDOC® CFC has been developed as a future-oriented concept for reverse engineering of e.g. Freelance function plans. Furthermore, function plans can be changed with the CFC editor.

  • Design and editing of function plans with  CFC editor according to EN 61131-3 resp. IEC 61131-3
  • Comparison of FUP versions
  • Reverse engineering of process control systems in CFC presentation

PLSDOC® CFC - editing and reverse engineering of CFCs


  • Customizable CFC library
  • Identification of changes concerning CFC designs
  • Automated reverse engineering of PCS software and output in CFC design
  • Increased plant security: perfect reverse engineering minimizes the risks arising from plant maintenance
  • Transparency as a result of revision adminstration: traceability of different versions
  • Reduction of operating costs: e.g. support of audits or software engineering (planning & monitoring of realizations)
  • Cost-neutral system documentation: reverse engineering of for instance 3000 measuring points can save more than 750 hours of work
  • Support for PCS migration


  • Comfortabe design and editing of function plans with the CFC editor
  • Reading and display of existing logics in process control systems, e.g. of Freelance
  • CFC/SFC delta function: provides comparsion between CFC versions including graphical visualization of the changes
  • Administration of revisions
  • Design and editing of CFC/SFC plans with the CFC editor
  • Import interface for ABB Freelaqnce, Emerson, Delta V ...


  • Central, database-oriented system documentation in CFC presentation
  • Generation of HTML and PDF documents
  • CFC/SFC editing with CFC editor
  • Multi-project and multi-user functionality
  • Company-wide solution
  • Menu-guided installation by users possible
