- This project was fairly methodical to implement on the PLC given the skill base built over the course so far. This makes a lot of sense given that PLCs are purpose built for industrial automation and control with their inbuilt functions geared accordingly.
- Access to resources, primarily the PLCs themselves, was the biggest hindrance to the project timeline.
- It was somewhat challenging being a large group of busy people with a relatively short time frame before delivery.
- Some areas of understanding how to really implement the process as a real simulation of a system were quite complex.
- Was fairly large learning curve on figuring out how to configure MPI and how to connect the HMI.
- During final compilation of the program the Murdoch Student Servers crashed hindering our finish time for the project putting it back to the last day.
- Active fail-over to another controller PLC which will assume control if certain condition(s) are met.
- A higher order filter could be used to reject more of the noise on the process variable (PV).
- A discrete beta filter or moving average could also be considered to better filter the PV noise.
- A higher order process could be implemented with relative ease given the implementation of 5 value shift registers.
- Better HMI interface for more user friendly interaction.
- Sending data through Siemens transfer functions like Send/Receive.
