Development Of A Relay Ladder Logic Programming And Simulation Tool With Graphical User Interface

• "Point and Click" graphical user interface based ladder logic program construction. • Forward Interpretation: The generation of an English-like representation of the control logic embodied by the ladder logic program. • Backward Interpretation: The generation of a ladder logic program from English-like control logic statements. • The use of assignable English device names in place of device addresses. • The generation of PC based data acquisition card device control code.
