Yesterday i had some extra time to work on my PLCBUS driver. Being able to monitor the ‘quality’ of my powerline seemed like a good idea, since PLC protocols always seem to suffer from noise produced by electrical devices like TV’s, computers, fluorescent lights etc. So it’s very handy to have a good insight in what is goig on on your powerline.

Since
all PLCBUS modules can report Signal and Noise level, i decided to
implement querying the modules to report Signal and Noise level at a timed interval.

Here’s what it looks like on my web site:

I also made a Signal Level chart for a PLCBUS module that’s currently located in my office, for testing purposes.
