S7-300/1200/1500 CPU webserver:
Advantages: "free", no extra hardware, does not add non-industrial equipment into the application.
Disadvantages: Programming is not as easy as a dedicated HMI solution. Any change to the webserver requires a hw download and stop of the CPU.

I think this is the kind of application that would be fine to do with the CPU webserver.There is no fancy graphics or animation. A few multi-color lights and some timer data.
