Abstract
To achieve ever-increasingly complex system functionality, modern machine control systems heavily count on software tools. Control software's primary purpose is to ensure correct execution of machine tasks in real time. DiagramDraw is proposed as a state machine modeling prototype. It is designed to help designers generate a state machine diagram and convert it to industrial sequence control programs for various industrial automation projects The tool has been built on its early version that was designed to deal with some particular industrial systems with a specific number of states. The new features and applications of DiagramDraw, in control design automation are discussed in this paper. This developed tool can help designers produce a state machine and needed control programs correctly and quickly.
