Slideshow A few weeks have passed and the Hook Norton Brewery effluent project has come to an end.

Today we commissioned the system and monitored its performance. The previous few days had been gathering data from the hardware and software to determine software variables such as water flow, tank height/ pressure and PID control variables.

The HMI was developed to allow system control over tank height and for the user to view historical data such as flow rates and overall volume output per day (required by Thames Water)

The pictures below show some of the hardware and how the HMI looks. Overall I am very satisfied with the work and we expect to be hearing back from the brewery after a few days to ensure that they are also satisfied with the system.

During the project I was given great responsibility over the PLC program and it is almost entirely my own work, only seeking help with PID control. This was quite a success as I had only worked with structured text previously in my Part C project at university so Ladder Logic programming was new to me. I am definitely looking forward to working with PLCs again in the future, as the end result is very satisfying.
