Abstract
A process control system includes a user interface which supports multiple IEC-1131 standard control languages and user-selection from among the control languages. From a single application routine, a user selects a control language from among a plurality of control languages including, for example, Function Blocks, Sequential Function Charts, Ladder Logic and Structured Text, to implement a control strategy.
