Might also look into some of the cards from Measurement Computing.  I'm
using a 96 bit card from them that one of my coworkers spent about a day
and wrote a basic driver for.  Seems pretty simple, and there are cards
with 24,48,and 96 bits of input and output.  Plugs directly into SSR
relay racks, also.

Jiro,

You may want to look into the Acromag ES2113 discrete I/O device.  It 
supports ModTCP and I have been able to get it working with the Modbus

driver written by Mark Rivers for Asyn.  You would need to provide 5v
pull 
ups for the ES2113 and I'm unsure of your timing constraints so I can't

be sure if it would work for you.

I do have some performance specs that I made when I was working 
with the ES2113 this summer if you are interested.

Have a good day!
