ABSTRACT:
A system for creating a program for a programmable logic controller (PLC). The user inputs a ladder logic command in an alphanumeric format, and the system creates a corresponding ladder logic graph on a display means. The user may then verify the relationship depicted in the graph, before forwarding the ladder logic command to the PLC.
