Produce a report critically analysing how each example PLC program makes use of PLC instructions. For each application you should discuss the use of the following features in PLC, annotating diagrams and structures

You have been working as the apprentice engineer at a company which develops and design PLC program for various other firms who need to automate their process. Vocational Scenario or You have been asked to investigate, design and develop a Context PLC system for Packaging Line control unit. The directors want you to prepare a report that can be given to a range of staff at the company. Task 1 As you have now researched two existing systems, the directors have asked you to investigate further using a research and development grant they have been awarded. You are to use example programs to investigate how PLC instructions are used to efficiently control system outputs. Produce a report critically analysing how each example PLC program makes use of PLC instructions. For each application you should discuss the use of the following features in PLC, annotating diagrams and structures where appropriate: Integrate Development Environments Ladder diagrams Statement listing (Instruction List program using Siemens) Graphical programming languages like Functional diagrams Mimic diagrams (Wiring Diagram) Sequential function charts (SFCs) Timers Counters Motion Comment on the efficiency of the programs, commenting on the use of subroutines and procedures. Checklist of evidence required A report on the use of PLC features including timers, counters and motion, as well as ladder diagrams, statement listings, functional diagrams, source code, mimic diagrams and sequential function charts
