Rough industrial setting (temperature > extremes, electrical noise, etc). We'd probably by COTS hardware, but If you are looking to reduce hardware expenditures, I know of at least one engine controller that was done for the navy using PC-based hardware and GE Fanuc I/O control blocks. On the ship shock and vibration was our main concern, so we found a moderately rugged touchscreen PC with PCMICA support, and replaced its hard drive with a solid-state PCMCIA hard drive. With a bit of hoofwork by your EE/ME folks, you might be able to come up with some PC-based solutions that will work in your environment. But the neat thing is that it ran NT (insert laughter here). Yeah, yeah, I know; but that meant we had a relatively large range of tools and vendors to choose from for our software development environment. -- T.E.D.
