I work for a Material Handling SI. As you can imagine, our systems use drives, motor starters, pneumatics, and I/O...a lot of I/O, all networked together. My boss asked me to look at how we can cost-reduce our systems, but of course keep all the functionality. Right now we're spending a lot of money on products that connect right to DeviceNet. For larger conveyor sections, we have to install more DeviceNets because we're running out of node addresses. I/O isn't the problem, it's the valves & motor starters that are chewing up our node addresses. I've heard about starters & valves that plug right into machine-mount I/O. The idea sounds like it could help me save a network connection and maybe keep from having to install more networks. But, we really need the constant feedback on the health of all the components. Does anyone know who's making these kind of products? Can this save me money and still give me the starter & valve diagnostics that DeviceNet gives me?
