you might want to have a look at the following site http://www.iba-ag.com/products/index.php?ptype=online&dlgroup=PDA&ID=802&level=3 these guys have products you can set up on the bus as a bus spy and grab the IO data as it comes across profibus etc. Also there arecards as well for direct connection to digitals inputs and analogs etc as well. with their equipment you can get sample rates down to 1ms. so have a look and see if there is anything you like or at least get some ideas of the type of gear you might like to use. |
