HIGH LEVEL PLC LANGUAGE AND DEVELOPMENT SYSTEM

Abstract

The "PlV" high level PLC language developed in the Department of Measurement Engineering, Technical University of Budapest, ensures bit, byte and word processing, the possibility of symbolic I/O and internal variable names, single line expressions, IF-THEN- ELSEIF-ELSE conditional structures and state transition graph structures. The development system makes the line-by-line correction possible and ensures a PlY language level debugger with built in LSS (logic state store).
