    Best Fieldbus for Discrete Instruments (On-off valves)?

    You could install Remote I/O stations with AS-i controllers. Use copper to link up the stations within the same process area. Use fiber optic to link up Remote I/O stations back to central control. The cost of equipment will be high, but you will also save on cabling (material & Labour)
