Task $1$

To ensure the best solution goes forward you need to prepare a report for your engineering team containing an analysis of the characteristics and internal architecture of a typical PLC and its key advantages over traditional relay logic and micro$-$computer control for this type of application.

To satisfy IEC$61131-3$ compliance you will also have to explain three different types of programming languages available to program the system.

One of the benefits of modern PLCs is the ease of interfacing to the real world for reliable operation. So you will need to determine $($with examples$)$ the input and output devices that are potentially available for the proposed system.

Further to this you need to consider that PLCs come in a variety of sizes and styles so describe the key differences of modern PLCs giving a typical example of each.

Finally, since PLCs often require interfacing to a computer and potentially a display panel, you should describe the different types of communication links available on modern PLCs$.$
