Foundation Fieldbus

Foundation Fieldbus

This series is an all-digital, serial, two-way communications system that serves as the base-level network in a plant or factory automation environment. It is an open architecture. Two related implementations of foundation fieldbus have been introduced to meet different needs within the process automation environment. These two implementations use different physical media and communication speeds.

  • H1 generally connects to field devices. It provides communication and power over standard twisted-pair wiring. H1 is currently the most common implementation.
  • HSE (High-speed Ethernet) generally connects input/output subsystems, host systems, linking devices, gateways, and field devices using standard Ethernet cabling. It doesn't currently provide power over the cable.
