Has Anybody - RS485

Has anyone built a multiprocessor system using RS485 to talk between units?

I'm constructing a system that is built up of smaller sub-systems controlling it's own small process of the machine.

Each sub-system seems to be fine on it's own, but I'd like to make a 'master' that orchestrates the entire process and reports back to / gets commands from a HID.

Maybe even a net server that users could log into for reports [noparse][[/noparse]using the interweb and any browser]

Currently my 'master' just monitors the I/O of the sub systems [noparse][[/noparse]as needed i.e. counts how many time an air cylinder is fired for production count]
so, 'upgrading' to a multidrop serial bus would allow unlimited reporting with less wiring [noparse][[/noparse]and noise issues].

... just food for though ...

    Also in Nut & Volts Column #146 they use RS485 and in column 147 is all about networking based around RS485, and from the sound of its right up the same ally as what your doing.

    The PDF file is the article and in the zip file you will find all the support files for that article.
