I once did something similar to control a rack full of Opto-22
sensor/output modules. I used an ethernet-connected RS-485 controller
(NEMA 4X-rated -- if I'm remembering correctly, it was made by Black
Box), and a NEMA 4X-rated ethernet -> 802.11b bridge box. The module
holders were daisy chained off each other with RS-485.
