ClearSCADA

ClearSCADA supports four of the languages included in the International Electro-technical Commission (IEC) standard for programming industrial control systems (IEC 1131-3):

  • Ladder Diagrams
  • Function Block Diagrams (FBDs)
  • Sequential Function Charts (SFCs)
  • Structured Text programs (ST)

In ClearSCADA these languages are referred to as Logic programs, and you can use them to:

  • Define complex relationships between the values for the properties of items in the database
  • Perform calculations
  • Execute methods on items in the database (one shots, overrides, controls etc.)
