We have a customer that is considering a Foundation Fieldbus system. They'd like our new machines to comply. Does anyone have ideas on how to handle discrete inputs/outputs, e.g., position switches, solenoid outputs, etc.? We both would prefer to stick with one communications protocol rather than using FF for analog signals and something else for discrete signals. I heard some vendors are developing a module that accepts discrete inputs/outputs onto FF. Does anyone know if this is on the market? If so, any results to date?
