Hi Stuart, Not that this is much help, but I had a look at doing the same thing. The other answers are correct - Brooks do offer a DDE based solution to communicate to their controllers. Unfortunately I wanted to use Labview RT (not Windows based), and therefore the DDE solution was not feasible.
I had a look at writing my own drivers using RS 485 and the Hart based protocol, but this seemed like too much work for our time frames. I ended up ordering the controllers with DeviceNet communications option. The Brooks manual for this seems pretty good, and I am busy developing the application. good luck with the drivers, Regards, Ravid
