PLC Assignment Report: State Machine Design and Implementation

This report presents a PLC assignment focused on state machine design and implementation. The assignment includes a detailed analysis of the system's behavior, the creation of a state diagram, and the development of ladder diagrams for the state sequence controller, transitions decoding, and output logic sections. The report also covers the initialization section and provides a PicoSoft printout of the design. It emphasizes the importance of clear documentation, including partial screen dumps of the ladder logic and descriptions of the testing procedures. The report follows a structured format, adhering to specific instructions regarding font size, line spacing, and submission guidelines. This assignment aims to demonstrate a practical understanding of PLC programming and control system design.

Section 4. PicoSoft printout. (10 marks)
Use Picosoft to generate a printed report for your design, including whatever options you think
appropriate.
Assignment hand in instructions.
Print out this document and the Picosoft printout double sided.
