In SIMATIC PCS 7 Plant Automation Accelerator (PAA) we distinguish between 3 different types of references (Textual reference, globale data reference and block variable reference), and connections.
 TypeShort description 
Textual reference
  • One of the parameters to be connected is not yet available or ready for use but will be released or created later.
  • Textual references can be entered in Connection manager by keyboard or by Drag&Drop

  • Textual references can be specified as absolute or relative.

  • Textual references can be exported from and to Excel

  • Textual references can be closed in Connection Manager and will then become connections

  • Textual references can be created graphically and are displayed yellow in the function diagram

  • Block variable references can be entered in Connection manager by keyboard

  • Block variable references can be exported from and to Excel

  • Block variable references must be closed in PCS 7
